hot jupiter

Hot Jupiters (also called roaster planets,[1]epistellar jovians,[2][3]pegasids[4][5] or pegasean planets) are a class of extrasolar planets whose characteristics are similar to Jupiter, but which have high surface temperatures because they orbit very close[6]—between approximately 0.015 and 0.5 astronomical units (2.2×10^6 and 75×10^6 km)—to their parent stars,[7] while Jupiter orbits its parent star (the Sun) at 5.2 astronomical units (780×10^6 km), causing low surface temperatures.

Astronomers, financially backed by NASA, have for the first time ever discovered tantilizing evidence that planets can form and exist around sun-like stars, densly packed together in star clusters. The finding is of significant importance, as scientists claim that it shows that planet can indeed exist in extremely harsh environments, like star clusters. The two [...]

Extrasolar hot Jupiter sheds some light on our own solar system

Since 1995, over 500 planets that don’t orbit our Sun have been discovered, with the numbers increasing more and more in the past years. But only recently did astrophysicists observe that in some of these cases, the star seems to be spinning in one direction, and the planet orbits it in the totally opposite direction [...]

Astronomers upset the theory of planetary formation

The discovery of 9 new planets raises some serious questions on the matter of how planets are formed. Two astronomers from the University of California, Santa Barbara reported the discovery, and of them, two are spinning in the opposite direction the planets in our solar system are spinning. This, along with other recent studies of [...]
