Two planets and six moons spin backwards compared to the others in our solar system. Due to the laws of inertia, all planets should move and spin in the same direction around the sun, All planets travel eastward around the sun, as expected. Venus, Uranus and Pluto’s spin is opposite to the other planets and the sun. These planets could not have ‘evolved’ as ejected material from the sun as some scientists claim. They may have been ‘captured’ as stray objects in space getting too close to our sun and hooked by it’s gravitation. Very unlikely. Most likely they spin the way they do because they were created this way.
