Johnson Solar System Ticket Out

Explanation
The asteroid belt is located between Mars and Jupiter in our solar system. This region is characterized by a large number of small rocky bodies called asteroids, which orbit the Sun. The gravitational influence of Jupiter prevented the formation of a planet in this region, leading to the accumulation of asteroids instead.

Explanation
The correct answer is Mars, Earth, and Venus. Terrestrial planets are rocky planets that are similar in composition to Earth. They have solid surfaces and are closer to the Sun compared to gas giants like Jupiter and Uranus. Mars, Earth, and Venus fit this description as they are all rocky planets with solid surfaces and are located within the inner solar system. Uranus, on the other hand, is a gas giant and does not meet the criteria of a terrestrial planet.

Explanation
There is only one star in our solar system, which is the Sun. The other options are not correct as there are no other stars in our solar system.

Explanation
The Sun is at the center of our solar system. It is a massive ball of hot, glowing gases that provides heat and light to all the planets, including Earth. The Sun's gravitational pull keeps all the planets and other celestial bodies in orbit around it. It is the primary source of energy for life on Earth and plays a crucial role in maintaining the balance of the solar system.

Explanation
Mercury and Venus are the planets that are less than one astronomical unit away from the sun. An astronomical unit (AU) is the average distance between the Earth and the sun, which is approximately 93 million miles or 150 million kilometers. Mars, Saturn, and Earth are all further away from the sun than one AU.

Explanation
The best unit to measure the distance from the Earth to Pluto would be astronomical units. This is because astronomical units are a commonly used unit in astronomy to measure distances within the solar system. One astronomical unit is equal to the average distance between the Earth and the Sun, which is about 93 million miles or 150 million kilometers. Since Pluto is also a part of the solar system, using astronomical units would provide a more accurate and convenient measurement for this specific distance.

Explanation
The correct answer is Jupiter---Saturn---Uranus---Neptune. The outer planets are those that are located farther from the sun than the inner planets. In our solar system, the outer planets are Jupiter, Saturn, Uranus, and Neptune. Therefore, the correct order of the outer planets starting from the closest to the sun out is Jupiter, Saturn, Uranus, and Neptune.

Explanation
Earth is the only planet in the given options that can support life. It has a suitable atmosphere, water, and a moderate temperature range that allows for the existence of various forms of life. Mars, although being the most habitable planet after Earth, lacks a breathable atmosphere and liquid water on its surface. Neptune is a gas giant with extreme temperatures and harsh conditions, making it unsuitable for life. Mercury, on the other hand, is a rocky planet with extreme temperature variations, making it inhospitable for life.

Explanation
The given correct answer states that the planet in question is an outer planet and a gas giant. This means that the planet is located further away from the Sun compared to the inner planets, such as Mercury, Venus, Earth, and Mars. Additionally, gas giants are characterized by their large size and predominantly composed of gases, such as hydrogen and helium.

Explanation
Mercury has the shortest orbit among the given planets. This is because Mercury is the closest planet to the Sun, which means it has a smaller distance to travel in its orbit. The closer a planet is to the Sun, the faster it moves in its orbit. Therefore, Mercury completes its orbit around the Sun in the shortest amount of time compared to Earth, Mars, and Jupiter.
