### Kepler’s Laws of Orbital Motion [1]

Kepler’s laws show the effects of gravity on orbits. They apply to any object that orbits another: planets orbiting the Sun, moons orbiting a planet, spacecraft orbiting Earth.
The Sun (or the center of the planet) occupies one focus of the ellipse. A focus is one of the two internal points that help determine the shape of an ellipse
Kepler’s Second Law Describes the Way an Object’s Speed Varies along Its Orbit. A planet’s orbital speed changes, depending on how far it is from the Sun

### How far are the planets from the Sun? [2]

The eight planets in our solar system each occupy their own orbits around the Sun. They orbit the star in ellipses, which means their distance to the sun varies depending on where they are in their orbits
So to talk about how far the planets are from the sun is a difficult question, not only because their distances constantly change, but also because the spans are so immense—making it hard for a human to grasp. For this reason, astronomers often use a term called astronomical unit, representing the distance from the Earth to the Sun.
– Closest: 46 million km / 29 million miles (.307 AU). – Furthest: 70 million km / 43 million miles (.466 AU)

### Imagine the Universe! [3]

The image of the Solar System was made using real images of the planets. It is not to scale; the Solar System is so large with respect to the size of the planets, that to fit it on the screen, the planets would have to be small dots
One way to help visualize the relative distances in the solar system is to imagine a model in which the solar system is reduced in size by a factor of a billion (109). The Earth is then about 1.3 cm in diameter (the size of a grape)
Jupiter is 15 cm in diameter (the size of a large grapefruit) and 5 blocks away from the Sun. Saturn (the size of an orange) is 10 blocks away; Uranus and Neptune (lemons) are 20 and 30 blocks away

### How far is Earth from the sun? [8]

Earth travels around the sun in an orbit that is slightly oval-shaped, known as an ellipse. Therefore, the planet’s distance from the sun changes throughout the year.
Scientists also call this distance one astronomical unit (AU).. The universe is a big place, and sometimes researchers use the astronomical units to communicate how far celestial objects are separated from one another
In early January, Earth reaches its closest position to the star. Astronomers call this point perihelion, and at this time Earth is about 91.4 million miles (147.1 million km) away from the sun, according to NASA.

### Read the passage and mark A, B, C or D to indicate the correct answer to each of the questions. [9]

Read the passage and mark A, B, C or D to indicate the correct answer to each of the questions.. Jupiter is the largest and most massive planet and is fifth in order of distance from the sun
Jupiter’s less than 10 hour rotation period gives it the shortest day in the solar system in so far as the principal planets are concerned. There are no true seasons on Jupiter because the axial inclination to the perpendicular of the orbital plane is only just over 3°-less than that for any other planet.
It has shown variations in both intensity and color, and at times it has been invisible, but it always returns after a few years. At its greatest extent it may be 40,000 kilometers long and 14,000 kilometers wide, so its surface area is greater than that of Earth

### Titius–Bode law [10]

The Titius–Bode law (sometimes termed simply Bode’s law) is a formulaic prediction of spacing between planets in any given solar system. The formula suggests that, extending outward, each planet should be approximately twice as far from the Sun as the one before
It is named after Johann Daniel Titius and Johann Elert Bode.. Later work by Blagg and Richardson significantly revised the original formula, and made predictions that were subsequently validated by new discoveries and observations
The law relates the semi-major axis of each planet outward from the Sun in units such that the Earth’s semi-major axis is equal to 10:. where such that, with the exception of the first step, each value is twice the previous value

### Radial velocity [11]

We often picture our Solar System with the Sun in the middle, completely stationary, while all the planets move around it. However, this isn’t true – in reality, the planets and the Sun orbit their common centre of mass
In this situation, the centre of mass will lie somewhere between the centre of the star and the centre of the planet. As the star is always more massive that the planet, the centre of mass will always lie closer to the centre of the star (this point often lies inside the star itself but displaced slightly from its centre)
The important thing to note though, is that the star does move.. The star’s movement towards and away from us causes its light to be Doppler shifted

### Kepler’s Three Laws [12]

In the early 1600s, Johannes Kepler proposed three laws of planetary motion. Kepler was able to summarize the carefully collected data of his mentor – Tycho Brahe – with three statements that described the motion of planets in a sun-centered solar system
Kepler’s three laws of planetary motion can be described as follows:. – The path of the planets about the sun is elliptical in shape, with the center of the sun being located at one focus
– The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun. Kepler’s first law – sometimes referred to as the law of ellipses – explains that planets are orbiting the sun in a path described as an ellipse

### Universal law [13]

A mathematical relationship between planets in our solar system holds astoundingly true even for 3 distant planets orbiting a pulsar. PLANETS in our solar system share a mysterious mathematical relationship
This cosmic beat, called Bode’s Law, holds true as far as the orbit of Uranus; but nobody knew why, and whether it was unique to our solar system.. But the recent discovery of 3 planets orbiting a pulsar known as PSR B1257+12 has revealed a system that remarkably mimics the spatial rhythm of our inner solar system comprising Mercury, Venus and Earth
PSR B1257+12 is a rapidly spinning, pulsating neutron star, slightly heavier than the Sun but more than a million times denser — its matter is packed into a sphere only 10 km across. Thought to have formed from the remains of a companion star mauled by the pulsar in question, the 3 planets cannot be seen directly, but are revealed by the manner in which they change the period of the pulsar’s pulses as they orbit around it.

### Sun [15]

The sun is an ordinary star, one of about 100 billion in our galaxy, the Milky Way. The sun has extremely important influences on our planet: It drives weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis.
The sun has extremely important influences on our planet: It drives weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis. Without the sun’s heat and light, life on Earth would not exist.
A nearby supernova emitted a shockwave, which came in contact with the molecular cloud and energized it. The molecular cloud began to compress, and some regions of gas collapsed under their own gravitational pull

### [Solved] Which of the following order of planets is correct as per di [16]

Which of the following order of planets is correct as per distance the increasing order from the Earth?. The correct answer is Venus, Mars, Mercury, Jupiter.
– Various data related to planet distance has been changed in recent findings but that is not widely accepted. So we are accepting the SSC answer as a genuine source.
– Inner planets (Mercury, Venus, Earth, and Mars) are called terrestrial planets because their structure is similar to the earth.. – Outer planets are represented as the planets after an asteroid belt i.e Jupiter, Saturn, Uranus, and Neptune.

### IELTS General Reading free samples. Sample 1.1 [17]

You should spend about 20 minutes on Questions 1–13, which are based on Reading Passage 1 below.. (A) The Earth is the third planet from the Sun and it is the only planet known to have life on it
(B) The large mass of the Sun makes the Earth move around it, just as the mass of the Earth makes the Moon move around it. The Earth also turns round in space, so different parts face the Sun at different times
(C) The Moon goes around the Earth about every 27⅓ days, and reflects light from the Sun. As the Earth goes round the Sun at the same time, the changing light of the Moon takes about 29½ days to go from dark to bright to dark again

### What is the order of the planets in the Solar System? [18]

What is the order of the planets in the Solar System?. Our Solar System has eight planets which orbit the sun
Pluto, which until recently was considered to be the farthest planet, is now classified as a dwarf planet. Additional dwarf planets have been discovered farther from the Sun than Pluto

### Sidewalk Solar System [19]

How far away is “next door” in space? The distances we experience here on Earth are far smaller than those out in space. Even in our planetary neighborhood, the solar system, the other planets are so far away the distances are hard to comprehend
Topics: solar system, scale distance, planets, models. – Sidewalk chalk or 10 objects to mark planet locations (for methods 2 & 3)
Make some predictions about how far apart the planets will be in your model. How far do you think your solar system will stretch across your yard or down your street? If Mercury is one toilet paper square away from the sun, how far away will Pluto be?

### What Are Perihelion and Aphelion? [20]

(Did You Know: The point in the Moon’s orbit that is closest to the Earth is called the “perigee,” and the point farthest from the Earth is known as the “apogee.”). In 2023, Earth will be 91,403,034 miles away from the Sun at perihelion and 94,506,364 miles away from the Sun at aphelion
Are Aphelion and Perihelion what cause the Seasons?. It’s not the distance from the Sun that causes our seasons
It’s because Earth orbits the Sun on a tilt that our planet gets more or less of the Sun’s direct rays at different times of the year. Though aphelion and perihelion are terms mostly used in reference to Earth since it’s our home planet, they are also relevant to other planets orbiting the Sun
