There might be coz NASA will do a mission to explore Ceres & vesta the dwarf planets and the mission is called "The Dawn Mission" and they will know if there is life by 2015 ;) Posted by:pokefreak0986 From YouTube.com
He discovered Ceres, the largest member of the asteroid belt
Giuseppe Piazzi, the Sicilian monk-astronomer who discovered Ceres in 1801, first suggested the name Ceres Ferdinandea - Ceres after the Roman goddess of plants, and Fredinandea after the then-presiding King Ferdinand III of Sicily. As other nations did not agree with the political part of the name, it was dropped and Ceres remained.
You must be American. Just a wild guess.
Ceres was discovered on January 1 1801 by Giuseppe Piazzi.It is the smallest dwarf planet.It is the only dwarf planet in the Asteroid belt.It is named after the Roman goddess Ceres, the goddess of growing plants, harvest, and motherly love.It is too small to see with the naked eye.The NASA Dawn space probe will explore Ceres in 2015.See related link for more information
Now, if we knew that, then we wouldn't need to do the research, would we?
Uh, no - see link.
It didn't - the planet Saturn was observed in ancient times, but Galileo was the first to view it through a telescope and discover its rings in 1610.
A dwarf planet located in the asteroid belt between Mars and Jupiter. It was discovered in 1801 and is the largest object in the asteroid belt. It has a diameter of approximately 950 km and is composed of water ice and rock. NASAβs Dawn spacecraft visited Ceres in 2015 and found evidence of a subsurface ocean.
