How big is the solar system?

The Solar System is just a planetary system in the vast vast universe. The planetary system has the Sun in the center and eight planets with nearly circular orbits within the Sun's gravity range. Taking our Earth as a benchmark, let's compare how massive the planets in the solar system are, the distance between them and how big the Sun is. From there, we can imagine how large the Solar System is called the Solar System.

1. How fast can a rocket fly to win gravity and escape the Earth?
2. What happens if the plane takes off on 8 planets in the solar system?

Compare the size of planets in the Solar System

1. Earth, our green planet has a diameter of 12,742km.
2. The Sun is 109 times the diameter of the Earth.
3. Mercury has a diameter of 0.38 times that of the Earth.
4. Venus is about the same size as the Earth, with a diameter of 0.95 times.
5. Mars is about half the size of the Earth, with a diameter of 0.53 times.
6. Jupiter has 11 times the diameter of Earth.
7. Saturn has a diameter of 9.4 times the Earth.
8. Uranus and Neptune are four times the diameter of the Earth.
9. Pluto dwarf planet - Pluto is 0.18 Earth in diameter.

Among these objects, Pluto is far from the Sun with a distance of 39.5 AU and nearest to Mercury with a distance of 0.4 AU.

The distance between the Sun and the Earth is 1 AU approximately equal to 149,597,870,700 km. This is an astronomical unit to measure distances in space.
