See Venus meet up with Uranus in the sky tonight (March 31)
The solar system's hottest planet (Venus) and its coldest one (Uranus) will be in conjunction tonight (March 31), offering a rare opportunity for skywatchers.
Uranus is the seventh planet from the sun and the third-largest planet in the solar system. The blue-green gas giant has the coldest atmosphere of all the planets in the solar system. Uranus is the only planet in the solar system that orbits the sun on its side, and this extreme tilt is responsible for turning the planet's magnetic fields into a jumbled mess. So far only NASA's Voyager 2 spacecraft has studied the planet up close during a flyby in 1986, but researchers are still studying the planet with telescopes on and around Earth.
