It's been observed that they do, and scientific theories have been developed to show in quite a lot of detail how they do. Their forward speed stops them falling into the Sun under the force of gravity, but the gravity causes their paths to curve continuously towards the Sun.
The planets do not orbit the Earth, they orbit the sun.
All the planets in our solar system orbit the Sun, not the Earth.Mercury and Venus orbit between the Sun and the Earth's orbit.
There are no planets in orbit between Earth and the Sun. The innermost planet in our solar system is Mercury, followed by Venus, then Earth. The region between Earth and the Sun is occupied solely by asteroids and other small objects.
That means there are also other planets.
No it does notNo we are not the only planet in the galaxy we have 8 other planets to. if the earth and the moon was that close to the sun we wouldn't be living.
Simple. Gravity! The planets are dragged in by the gravity of the sun.
The sun's gravity keeps the earth and the other planets in orbit around it
orbit =)
It keeps them in orbit
the sun
The sun is the star in which Earth and the other planets in the solar system orbit.
Without the planets orbiting the sun all the planets would be cold and dark
