81 years ago, the PLANET Pluto was discovered. It wasn't reclassified as a "dwarf planet" until 2006.
well if u think about it logically..... Pluto, classified as a planet since its discovery, was reclassified as a dwarf planet only a few years ago.
formed 4.57 billion years ago
I believe they discovered a planet a couple of years ago, that they named Krypton, but i believe it has been downgraded since then to a dwarf planet or an asteriod. And I don't think it could sustain life. So no superman coming from that planet!
The planet Mercury was discovered around 3,500 years ago, Unfortunately the name of the person who discovered it was not recorded.
No. The planet was known about approx 3,500 years ago.
The planet Uranus was discovered in 1781 by William Herschel. That was about 129 years ago.
Mercury has been observed for thousands of years, as early as the time of the Babylonians, who mentioned it in writing some 3000 years ago. The exact person who first discovered the planet has been lost to time, and is therefore indeterminate.
it comes to our attention that the ancient planet of mercury was discovered by our amazingly advanced elders, the bablyonians, over three thousand years ago. =<(
Peppers were discovered about 6,000 years ago.
Nothing. You may be referring to the planet Pluto, which was DISCOVERED in 1930, but it had in all probability been part of the solar system since the Sun ignited 4.5 billion years ago.
Pluto was founded by ancient Greek astronomers thousands of years ago. So I'll go with Pluto the planet, despite it now being a dwarf planet.
Pluto is considered to be two different things. 1. Pluto is a dwarf planet. It is in hydrostatic equilibrium (round) and it orbits the sun, but it has not cleared its neighborhood of debris. What's its neighborhood? The Kuiper belt, a collection of icy objects similar to comets that somewhat resembles the asteroid belt. This leads to its second classification. 2. Pluto is a Kuiper Belt Object (KBO). Specifically, it's classified as a plutino - an object within a certain zone of the Kuiper Belt.
