Weight is equivalent to the largest planet Earth 2500.

"He led the team in the" Astrophysics "magazine published the findings. .</ P> <P align=left> team can turn it by the public to observe the planet to determine when it is something about its characteristics. .Bakos said: "We estimate that it is a great attraction is about 15 times the Earth." This means a 68 kg weight on the earth who, to the HAT-P-2b weight on the planet can reach 950 kg. .</ P> <P align=left> scientists believe the planet's density is very large, although the HAT-P-2b smaller than the planet Jupiter in our solar system's largest not much, but it is important than the Jupiter 8 .times the mass of the Earth is equivalent to 2500. .</ P> <P align=left> HAT-P-2b the distance around the star from its close, only 500 million km journey around only 1,500 kilometers, so it is the time required for one revolution on the planet as long as the equivalent of .5.6 days. .</ P> <P align=left> why this strange phenomenon, scientists believe there is a possibility that it may be still hidden around another planet. .</ P> <P align=left> Bakos said: "may HAT-P-2b, there are still around we have not found a planet interacting with it." </ P> <P align=left> Research .say, calculated over the conclusion that the density of strange planets should be able to exist, and this new discovery just to provide conclusive evidence. .</ P> </ p>.
