When you want to know more about something, you check it out, right? That’s exactly what scientists at NASA are doing.
They want to know more about an object in space they call Vesta. Is it an asteroid? A planet? What exactly is it?
Two months ago, they launched the Dawn spacecraft. Its job is to orbit and observe Vesta.
Vesta is officially listed by NASA as a “minor planet,” which means that it is an object orbiting around the sun.
But Vesta isn’t really a planet at all. It’s simply an object in space.
It has also been called an asteroid, a dwarf planet (a tiny planet), and a protoplanet, which is an object that started the same way as other planets, like Venus and Mercury, but never fully developed.
