Here's what to know about the short life of what was, for a single human lifetime, the solar system's smallest planet. When was Pluto discovered?

Today, let's talk about Pluto and Charon; these two have quite the story! Did you know that their 10-hour "intimate encounter" has shaken the field of astronomy to its core?

Pluto was discovered in 1930 in Arizona, but in 2006 scientists decided to cut Pluto from the planetary line up. Here is why Pluto isn't a planet.

Rather than a vast ocean, Pluto’s heart might be hiding a huge, heavy treasure. Computer simulations suggest that an object about 730 kilometers wide, slightly larger than the asteroid Vesta ...
