SOLAR SYSTEM

The solar system consists of the sun and all of the planets, as well as their satellites, dwarf planets, and small bodies (asteroids and comets). These all revolve around the sun, which is a star.

Which of our solar system’s planets rotates on its side?

Uranus is the answer.

What maintains the planets’ orbits around the sun?
The planets are kept in orbit by the force of gravity.

Which of the following planets has a large mass but a small inner core?
Answer: The planet Jupiter has a small core surrounded by a thick layer of gas.

Why does the planet Mars appear red?
The surface of Mars contains a lot of iron oxide, which gives it a rusted appearance.

Which planet in our solar system has the highest temperature?
Although Mercury is the closest planet to the sun, it lacks an atmosphere to trap heat. The hottest planet is Venus, which has a dense carbon dioxide atmosphere that traps heat.

The sun is the star closest to Earth. It’s a huge ball of hot, glowing gas. The sun is enormous, and its powerful gravitational field keeps our solar system’s planets in orbit. The heat and light of the sun enable life to exist on Earth.

The earth is just the right distance from the sun (about 93 million miles) to create the necessary conditions for life. The sun warms us and provides the energy that plants require to grow and produce food.

The sun is primarily made up of hydrogen gas. Fusion occurs when hydrogen atoms are squeezed tightly together inside the sun. Helium is produced by this fusion. Massive amounts of energy are released during the splitting of atoms. This energy takes the form of heat and light energy.
