Extrasolar planet
An extrasolar planet, or exoplanet, is a planet outside the Solar System. A total of such planets have been identified as of . It is now known that a substantial fraction of stars have planets, including perhaps half of all Sun-like stars...

Mass
Mass can be defined as a quantitive measure of the resistance an object has to change in its velocity.In physics, mass commonly refers to any of the following three properties of matter, which have been shown experimentally to be equivalent:...

Jupiter
Jupiter is the fifth planet from the Sun and the largest planet within the Solar System. It is a gas giant with mass one-thousandth that of the Sun but is two and a half times the mass of all the other planets in our Solar System combined. Jupiter is classified as a gas giant along with Saturn,...

HD 41004 Ab
HD 41004 Ab is an extrasolar planet approximately 139 light years away in the constellation of Pictor. It has mass 2.56 MJ planet orbiting at a distance of 1.70 AU from HD 41004 A. The planet's orbit is highly eccentric caused by the companion star HD 41004 B and the distance ranges from 0.44 to...

HD 65216 b
HD 65216 b is an extrasolar planet located approximately 116 light-years away in the constellation of Carina, orbiting the star HD 65216. This planet was discovered by the Geneva Extrasolar Planet Search Team in 2003. Like most planet candidates so far, it was detected with the radial velocity...

HD 169830 c
HD 169830 c is an extrasolar planet, most likely a gas giant, three and a half times as massive as Jupiter. It is likely to be smaller in radius but slightly larger than Jupiter. Its orbit is eccentric, with a period of 1830 days....

HD 216770 b
HD 216770 b is an extrasolar planet orbiting the star HD 216770. It has a mass about two thirds that of Jupiter, largest planet in our Solar system. But unlike the gas giants in the Solar system, it orbits in a very eccentric orbit around the star...

HD 10647 b
HD 10647 b, also catalogued as q1 Eridani b, is an extrasolar planet approximately 57 light-years away in the constellation of Eridanus . The planet is a mid-Jovian that orbits 103% farther from the star than Earth to the Sun. It takes about 33 months to orbit with semi-amplitude of 17.9 m/s.-...
