Why planet revolve in anticlockwise direction around sun?

Answer 1

Everything in the solar system rotates that way. Probably the primordial nebula was spinning that way before the solar system formed. Edit: Not everything. For an example, Venus moves clockwise and Neptune rolls.

Answer 2

This Q has two answers.

First, due to the Laws of Conservation of Momentum, the spin of the Earth is the residual nett spin left from the accretion (or from the impact of Theia ?).

Alternate hypothesis as to clockwise or not. Viewed from the centre of our Galaxy, i.e. above the South Pole, or at least the Southern Hemisphere, the rotation is clockwise.

[But maybe the folk in the centre of the Galaxy have their watches go the other way anyway!!]

Answer 3

All planets in our solar system revolve counter clockwise - frame of reference given as seen from above the north pole looking down; the exceptions are Venus which rotates clockwise (retrograde, or opposite the direction of its orbit) and Uranus which rotates on its side at about 98 degrees to the orbital plane.

The reasons for Venus's unusual rotation are variously attributed to the initial state of its formation from the solar nebula; perterbations from other planets, tidal forces including tidal locking effect from the Sun, and possible impact with another body that may have reversed its spin.

Answer 4

It's not really spinning clockwise or anticlockwise, strictly speaking. It depends on your orientation. The reason that they all orbit the sun in the same direction is because that's is the direction which the mass that made up the solar system was spinning to begin with.

Answer 5

That is the direction that they have been moving since the solar systems creation, The original cloud of gas and dust had a net rotational spin in that direction which has remained unchanged. It depends how you look at the solar system though and how you define directions in space. You could easily say that it spins the other way of you were to change your veiwpoint.

Answer 6

The counterclockwise direction of planets orbiting the Sun is believed to have been determined during the early stages of the solar system's formation from a rotating cloud of gas and dust. As the cloud collapsed under gravity, its overall rotation caused the resulting planets to also orbit in the same direction. This counterclockwise motion has been preserved over billions of years due to the conservation of angular momentum.

Answer 7

I don't think anyone knows or that's what my astronomy instructor says.
