Earth
Explanation
The Solar System consists of the Sun and eight planets that revolve around it in fixed elliptical paths called orbits. The position of each planet is defined by its distance from the Sun.
The sequence of the planets, in order of increasing distance from the Sun, is:
- Mercury
- Venus
- Earth
- Mars
- Jupiter
- Saturn
- Uranus
- Neptune
According to this arrangement, Earth is the third planet from the Sun and is positioned between Venus (the second planet) and Mars (the fourth planet).
Key Takeaway: The correct order of inner planets from the Sun is Mercury, Venus, Earth, and Mars.
