They are believed to be rocky, but their exact composition has not yet been determined. The existence of this system is fairly impressive, given the amount of raw materials available to work with at the time. In the beginning, the universe was pretty much just hydrogen and helium.

Timeline of discovery of Solar System planets and their moons

Stars formed, forged heavier elements like carbon and iron within their cores, spewed those elements out as they died. The cycle continued, with each generation of star producing more of the heavier elements necessary for planetary formation. This system tells us that planets were forming around stars nearly 7 billion years before our own solar system. The planet — a gas giant with three quarters the mass of Jupiter — is likewise probably still growing. That means it is acquiring more mass by frequently colliding with other planetary bodies like asteroids in its path — making it an unsafe place to be.

Because exoplanets are too far away for us to be able to observe any weather patterns we have to turn our eyes back to our solar system.

However, the title goes to Venus. A planet the same size of Earth, it is shrouded in clouds of sulfuric acid.

Double-eyed cyclones are sustained above each pole. Though bone-dry and hostile to life, the heat may explain why Venus has fewer volcanoes than Earth. A contemporary Robinsonade — York, York.

KELT-9B is the hottest known planet. Christian Schroeder , University of Stirling. The hottest How hot a planet gets depends primarily on how close it is to its host star — and on how hot that star burns. The biggest If a planet can be as hot as a star, what then makes the difference between stars and planets?

The smallest Just slightly larger than our moon and smaller than Mercury, Keplerb is the smallest exoplanet yet discovered. The oldest PSR B b, at NASA and G.

The youngest The planetary system V Tauri is only 2m years old. The worst weather Because exoplanets are too far away for us to be able to observe any weather patterns we have to turn our eyes back to our solar system. Well, again, probably not. And a short orbital period means that the planets are very close to the star. But then how can life possibly be much older than the 3 billion years that was mentioned in relation to Earth?

Well, these are just a small sample of the planets that exist in our universe. As such, it is entirely likely that other possibly even older worlds exist that could have had conditions favorable to life. Share to Facebook. Tweet This. Share via Email.
