But when the solar system formed it was revolving backwards.

and how can something rotate backwards but revolve normally?

No, it was revolving the same way as the other planets, and the same way it does today.

<p>I have heard that when our solar system formed that all planets except Venus were revolving around the sun in the same direction because of the normal rotation of their axes. Venus was rotating and revolving backwards or retrograde. There was a collision with Venus that caused it to rotate and revolve normally.</p>

<p>But why would a planet revolve backwards around a star relative to all the other planets in the stellar system?</p>

It's a bit unclear if you're asking about retrograde orbit (i.e. it completes a year clockwise around the Sun) or retrograde rotation of the planet along its own axis w.r.t. its orbit (completes a day clockwise)? A link to where you heard what you allude to in your question could help, please [edit] the question with additional details explaining what precisely are you asking.

Venus started with retrograde rotation?

(Asked by: username_0 on 2014-10-08)

I have heard that when our solar system formed that all planets except Venus were revolving around the sun in the same direction because of the normal rotation of their axes. Venus was rotating and revolving backwards or retrograde. There was a collision with Venus that caused it to rotate and revolve normally.

But why would a planet revolve backwards around a star relative to all the other planets in the stellar system?

You've confused its rotation and revolution. [Venus](http://en.wikipedia.org/wiki/Venus#Orbit_and_rotation) revolves around the Sun in the same way as all the other planets, but its *rotation* is in the opposite direction of theirs. It has retrograde rotation, but not revolution. I think this solves your paradox.
