Solar System Facts

The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed. Nearest to the Sun, only rocky material could withstand the heat when the solar system was young. For this reason, the first four planets – Mercury, Venus, Earth, and Mars – are terrestrial planets.

Mercury (planet)

Mercury is the first planet from the Sun and the smallest in the Solar System English, it is named after the ancient Roman god Mercurius (), god of commerce and communication, and the messenger of the gods.Mercury is classified as a terrestrial planet, with roughly the same surface gravity as Mars.The surface of Mercury is heavily cratered, as a result of countless impact

Venus Facts

The ancient Romans could easily see seven bright objects in the sky: the Sun, the Moon, and the five brightest planets: Mercury, Venus, Mars, Jupiter, and Saturn. They named the objects after their most important gods. NASA''s Magellan spacecraft, which ended a five-year mission to Venus in 1994, mapped the broiling surface using radar

Saturn

Project Mercury

Project Mercury was the NASA program that put the first American astronauts in space. Astronauts made a total of six spaceflights during Project Mercury. Two of those flights reached space and came right back down. These are called suborbital flights. The other four went into orbit and circled Earth. The first of those six flights was made in 1961.

Is a day on Mercury like a day on Earth?

A day on Mercury is not like a day here on Earth. For us, the Sun rises and sets each and every day. Because Mercury has a slow spin and short year, it takes a long time for the Sun to rise and set there. Mercury only has one sunrise every 180 Earth days! Isn''t that wild?
