If the mean distance of a planet from sun is 4 times the mean distance of
earth from sun, then how many years does that planet take to move once
around the sun?
answer this ASAP!!!!!
Answers
The sun is at the heart of the solar system. All of the bodies in the solar system — planets, asteroids, comets, etc. — revolve around it at various distances. Mercury, the planet closest to the sun, gets as close as 29 million miles (47 million kilometers) in its elliptical orbit, while objects in the Oort Cloud, the solar system's icy shell, are thought to lie as far as 9.3 trillion miles (15 trillion km). But what is the distance between Earth and the sun?
Earth orbits the sun 100,000 times closer than the Oort Cloud, at an average of 92,955,807 miles (149,597,870 km). The distance from Earth to the sun is called an astronomical unit, or AU, which is used to measure distances throughout the solar system.
Jupiter, for example, is 5.2 AU from the sun. Neptune is 30.07 AU from the sun. The distance to the nearest star, Proxima Centauri, is about 268,770 AU, according to NASA. However, to measure longer distances, astronomers use light-years, or the distance that light travels in a single Earth-year, which is equal to 63,239 AU. So Proxima Centauri is about 4.25 light-years away.
Answer:
Distance between Earth & Sun = 151.97 million km
Time taken = 365 and half days
Distance is 4 times that of earth = 607.88 million km
Time taken = 365 1/2 × 607.88 M / 151.97 M
