Final answer:
Planets are large celestial objects that revolve around a star, and there are eight planets in our solar system that revolve around the sun.
Step-by-step explanation:
Our solar system consists of eight recognized planets, listed in order of their distance from the sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. These planets follow elliptical orbits around the sun, driven by gravitational forces. The term "revolve" refers to the orbital motion of planets around the sun.
The eight planets in our solar system can be remembered using the mnemonic device "My Very Educated Mother Just Served Us Noodles," with the first letter of each word corresponding to the initial letter of each planet.
In conclusion, the eight planets in our solar system—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune—revolve around the sun in elliptical orbits. This organized motion is a result of the gravitational pull exerted by the sun, defining the structure and dynamics of our solar system.
