Why do planets travel around the sun in a circular path?

Answer 1

This is because of the gravational pull from the large size of the sun, just as if you had a weight in the middle of a trampolin it creates a dent in the fabric, celestial bodies also creates dents in the fabric of space-time, and if you throw another ball onto the trampoline it rolls around the weight in a cricle planets do the same.

Answer 2

The planets are not currently in alignment, but that does happen on rare occasion, as a result of orbits coincidentally matching. You are possibly trying to ask why the planets are all in the same plane, known as the plane of the ecliptic. That is because the solar system condensed out of a rotating interstellar cloud of gas and dust, and the rotation of the original cloud influenced the positions and motions of the resulting star and planets.

Answer 3

Each planet travels around the Sun in an elliptical path according to Kepler's first law. But most of the planets have an elliptical orbit with a very low value of eccentricity, which is very close to a circle. So you could answer the question by saying, because their elliptical orbits have low eccentricity.

Answer 4

According to Keplers first law of 1618 the planets each move in an elliptical orbit with the Sun occupying one focus. The shape of an ellipse is described by the eccentricity. For low eccentricity such as the planets' orbits have, the orbit is very close to being a circle but the most significant difference is that the Sun is off-centre. Because these ellipses are nearly circular, it took the best scientists more than a thousand years to discover that they are actually ellipses.

Answer 5

If the planets traveled in straight lines, then their orbits would be perfect
plus the gravitational pull is constantly getting stronger and weaker

Answer 6

i think its because its the gravitational pull of the sun that makes the planets orbit it.

Answer 7

due to the gravitational pull of the sun

Answer 8

Gravity - from the sun
