Latest Carbon planet Stories
What was believed to be the first-ever discovered planet to be comprised largely of diamond most likely does not have a high content of the precious mineral after all.
One nearby super-Earth planet could have a lot more "bling" on it than our planet, because astronomers say it maybe a diamond planet.
In the Star Wars movies, fictional planets are covered with forests, oceans, deserts, and volcanoes. But new models begin to describe an even wider range of Earth-size planets that astronomers might actually be able to find in the near future.
Some extrasolar planets may be made substantially from carbon compounds, including diamond, according to a report presented this week at the conference on extrasolar planets in Aspen, Colorado. Earth, Mars and Venus are "silicate planets" consisting mostly of silicon-oxygen compounds. Astrophysicists are proposing that some stars in our galaxy may host "carbon planets" instead.
Terrestrial Planet -- A terrestrial planet is a planet that is mostly composed of silicate rocks and may or may not have a relatively thin atmosphere. The term is derived from the Greek word for Earth, so an alternate definition would be those planets that are more Earth-like than not. Terrestrial planets are very different from gas giants, which may or may not have solid surfaces and are composed mostly of hydrogen and helium in various physical states. Only one terrestrial planet,...
