Mercury, Venus, Earth and Mars are four of the eight planets in our solar system. They are located at different distances from the Sun and have different characteristics.
Mercury is the closest planet to the Sun and therefore it has a very short orbital period of just 88 days. It is a small planet with no atmosphere and a heavily cratered surface.
Venus is the second planet from the Sun and is known as the hottest planet in our solar system with surface temperatures that can reach up to 460°C. It has a thick atmosphere that traps heat, causing a greenhouse effect.
Earth is the third planet from the Sun and is the only planet known to support life. It has a moderate climate with a complex atmosphere that provides oxygen for living organisms.
Mars is the fourth planet from the Sun and is known as the Red Planet due to its reddish appearance. It has a thin atmosphere and a cold, dry surface. Scientists believe that Mars may have once had water and a more habitable environment.

In the solar system
The solar system consists of the Sun and all the objects that orbit around it. This includes the eight planets - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune - as well as dwarf planets like Pluto, asteroids, comets, and other space debris. All the objects in the solar system are held in place by the Sun's gravitational pull and follow elliptical orbits around it. The solar system is located in the Milky Way galaxy, about 25,000 light years from the galactic center.
