Answer 1

The correct answer is Mercury

Key Points

Mercury is the planet in the solar system that is nearest to the Sun.
It is the smallest planet in the solar system and has no moons.
Mercury orbits the Sun at an average distance of about 57.9 million kilometers (36 million miles).
Due to its proximity to the Sun, Mercury has extreme temperature variations, with surface temperatures ranging from -173°C at night to 427°C during the day.
Mercury has a very thin atmosphere, composed mostly of oxygen, sodium, hydrogen, helium, and potassium.

Additional Information

Mercury has a heavily cratered surface, similar to the Moon, indicating it has been geologically inactive for billions of years.
The planet completes an orbit around the Sun in just 88 Earth days, making it the fastest orbiting planet in the solar system.
Despite its proximity to the Sun, Mercury is not the hottest planet in the solar system; that title goes to Venus, which has a thick atmosphere that traps heat.
Observing Mercury from Earth can be challenging due to its close orbit to the Sun, and it is often visible just before sunrise or just after sunset.
Space missions to Mercury include NASA's Mariner 10 and MESSENGER, which have provided valuable data about the planet's characteristics and environment.
