Amazingly, a single day on Venus is longer than its entire year. It takes Venus 243 Earth days to completely rotate on its axis, but just 225 days to orbit the sun. Stranger still, Venus is one of two planets that rotates in reverse, a phenomenon called retrograde motion. Most theories attribute the reverse rotation to an ancient planetary collision.

NASA Chief Scientist Predicts We'll Find Signs Of Alien Life By 2025
Earth isn't the only ocean world in our solar system. Oceans could exist in diverse forms on moons and dwarf planets, offering clues in the quest to discover life beyond our home planet. This illustration depicts the best known candidates in our search for life in the solar system. Image Credit: NASA/JPL-Caltech
This is the highest resolution image of Earth ever made, 121 megapixels. That’s an amazing 0.62 miles per pixel. It was taken by Russia’s latest weather satellite, the Electro-L, which is orbiting Earth on a geostationary orbit 36,000 kilometers above the equator, sending photographs of the entire planet every 30 minutes.
#SolarSystem facts : The Solar System consists of the #Sun and the astronomical objects gravitationally bound in orbit around it, all of which formed from the collapse of a giant molecular cloud approximately 4.6 billion years ago. 99.86% of the system’s mass is in the Sun.
