What colors are the planets in our solar system? And why are they so different?

The planets of the solar system are varied in their appearance. Mercury is slate gray while Venus is pearly white, Earth a vibrant blue, and Mars a dusky red.

As it turns out, stars and their planets form at the same time from a disk of gas and dust known as a solar nebula.

At the same time, debris mixed into the nebula collided over and over again, eventually accreting into planetesimals and then protoplanets.

If you ever wanted to help find new planets, now's your chance | Ars Technica

If you've ever wanted to search for distant worlds, your time has come. The team behind a planet-hunting telescope array called the Next-Generation Transit Survey (NGTS) is looking for help with the large volume of data the instrument has produced.

The team now has a lot of data, which it has sifted through using computers. But computers have difficulty distinguishing a likely planet from various sources of noise, so the researchers are asking the public to double-check the computers and provide a final call on what a signal is.

Astronomer's Stunningly Simple Animations Reveal Solar System Physics

So a few days before their study's publication, O'Donoghue slapped an expanding black circle onto an image of Saturn and faded most of its rings away. The New York Times featured his animation with the news of the study.

Then, as he continued to roam the Internet while waiting for government work to resume, O'Donoghue realized that he couldn't find any videos comparing each planet's spin side by side. So he made one.
