1.(Celestial Objects) Also called:major planetany of the eight celestial bodies, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, that revolve around the sun in elliptical orbits and are illuminated by light from the sun ...
Average distance from the sun: 67 million miles (108 million km). Perihelion (closest approach to the sun): 66,785,000 miles (107,480,000 km). Aphelion (farthest distance from the sun): 67,692,000 miles (108,941,000 km). If viewed from above, Venus rotates on its axis in a...
Mars orbits the Sun in 687 days, which means 1 Earth year on Mars is 687 days.【小题1】The distance from the Sun to Mars is fewer than 141 million miles.【小题2】Mars is one of the planets that can be seen from the Earth with a telescope....
Of the eight planets in the solar system, Mercury is theclosest planet to the sun. It is also the smallest planet only slightly larger than our moon. Despite being the smallest planet with a mean diameter of 3,032 miles (4,879 km), Mercury is the second densest planet. With the shorte...
Mars is much colder than Earth, in large part due to its greater distance from the sun. Theaverage temperatureis about minus 80 degrees Fahrenheit (minus 60 degrees Celsius), although it can vary from minus 195 F (minus 125 C) near the poles during the winter to as much as 70 F (20...

Earth - Planet, Atmosphere, Geology: The mean distance of Earth from the Sun is about 149,600,000 km (92,960,000 miles). The planet orbits the Sun in a path that is presently more nearly a circle (less eccentric) than are the orbits of all but two of the
Planet, broadly, any relatively large natural body that revolves in an orbit around the Sun or around some other star and that is not radiating energy from internal nuclear fusion reactions. There are eight planets orbiting the Sun in the solar system.
Planet Nine's composition is probably "most like Neptune," due to its distance from the sun, Brown said. "That would put its diameter at something like two times the width of Earth," he added. Some scientists have also suggested Planet Ninecould be surrounded by moons, just as the ...
