What is the closest planet to the sun? The number of planets in the solar system is eight, and they revolve around the sun at different times and speeds. They also differ in their sizes, density, number of moons, and compositions. And we will learn about the nearest planets to the sun, and the smallest and fastest planets in the solar system.
What is the closest planet to the sun?
The closest planets to the sun It is the planet Mercury. Also known as MercuryIt is an ancient Roman name derived from the god of trade. Mercury is also the smallest planet in the solar system, and even the fastest among the planets of the Milky Way. Especially since it is about 57,910.006.85 kilometers from the Sun, while it is about 82,000,000 kilometers from Earth. It should be noted that the four planets closest to the sun, Mercury, Venus, Earth and Mars, are called terrestrial planets.[1]

What is the planet Mercury?
Mercury is the closest planet to the sun, and there is no doubt that there is no life on Mercury, as it is famous for its very high temperatures, and perhaps this indicates the absence of life on Mercury. Mercury also lacks an atmosphere, and is classified among the small rocky planets. It also contains many cavities and craters, as its surface is the closest among the planets to the surface of the moon. Although it is one of the planets known to man since ancient times, that is, more than five thousand years ago, and was able to see it with the naked eye, astronomers were able to follow it and see it using advanced telescopes. Two spacecraft were also able to visit the planet Mercury: MARINER 10 and MESSENGER spaceships.[1]
