Exoplanets discovered in 2009

CoRoT-7b (previously named CoRoT-Exo-7b) is an exoplanet orbiting the star CoRoT-7 in the constellation of Monoceros, from the Earth. It was first detected photometrically by the French-led CoRoT mission and reported in February 2009. Until the announcement of Kepler-10b in January 2011, it was the smallest exoplanet to have its diameter measured, at 1.58 times that of the Earth (which would give it a volume about 3.94 times Earth's) and the first potential extrasolar terrestrial planet to be found. The exoplanet has a very short orbital period, revolving around its host star in about 20 hours

WASP-17b, officially named Ditsö̀, is an exoplanet in the constellation Scorpius that is orbiting the star WASP-17. Its discovery was announced on 11 August 2009. It is the first planet discovered to have a retrograde orbit, meaning it orbits in a direction counter to the rotation of its host star. This discovery challenged traditional planetary formation theory. In terms of diameter, WASP-17b is one of the largest exoplanets discovered and at half Jupiter's mass, this made it the most puffy planet known in 2010. On 3 December 2013, scientists working with the Hubble Space Telescope reported d

HAT-P-11b (or Kepler-3b) is an extrasolar planet orbiting the star HAT-P-11. It was discovered by the HATNet Project team in 2009 using the transit method, and submitted for publication on 2 January 2009.

WASP-18b is an exoplanet that is notable for having an orbital period of less than one day. It has a mass equal to 10 Jupiter masses, just below the boundary line between planets and brown dwarfs (about 13 Jupiter masses). Due to tidal deceleration, it is expected to spiral toward and eventually merge with its host star, WASP-18, in less than a million years. The planet is approximately from its star, which is about from Earth. A team led by Coel Hellier, a professor of astrophysics at Keele University in England, discovered the exoplanet in 2009.

WASP-19b, formally named Banksia, is an exoplanet, notable for possessing one of the shortest orbital periods of any known planetary body: days or approximately 18.932 hours. It has a mass close to that of Jupiter (1.15 Jupiter masses), but by comparison has a much larger radius (1.31 times that of Jupiter, or 0.13 Solar radii); making it nearly the size of a low-mass star. It orbits the star WASP-19 in the Vela constellation. At the time of discovery it was the shortest period hot Jupiter discovered as planets with shorter orbital periods had a rocky, or metallic composition.

CoRoT-7c is an extrasolar planet which orbits the G-type main sequence star CoRoT-7, located approximately 489 light years away in the constellation Monoceros. It is either a super-Earth or a Neptune-like planet, orbiting at 0.046 AU from the star, taking 3.7 days or 89 hours to make one round trip around the star.

CoRoT-6b (previously named CoRoT-Exo-6b) is an exoplanet that was discovered by the CoRoT mission team on February 2, 2009, orbiting the F type star CoRoT-6. It is located in the Ophiuchus constellation.

HAT-P-13b is an extrasolar planet approximately 700 light-years away in the constellation Ursa Major. The planet was discovered when it transited across its sun, HAT-P-13. This planet is a hot Jupiter with 0.851 times the mass of Jupiter and 1.28 radius. The planet has a lower mass, but its overall size is larger than Jupiter.

WASP-15b, formally named Asye, is an extrasolar planet discovered in 2008 by the SuperWASP collaboration, which seeks to discover exoplanets that transit their host stars. The planet orbits its host star at a distance of 0.05 AU every four days. The mass of this planet is about one half that of Jupiter, but its radius is nearly 50% larger than Jupiter's, making the density of this planet only one quarter that of water; it is thought that some other form of heating must explain its extremely low density. WASP-15b's discovery was published on April 29, 2009.

HAT-P-12b, formally named Puli, is an extrasolar planet approximately 468 light years away from Earth, orbiting the 13th magnitude K-type star HAT-P-12, which is located in Canes Venatici constellation. It is a transiting hot Jupiter that was discovered by the HATNet Project on April 29, 2009.

WASP-13b, also known as Cruinlagh, is an extrasolar planet that was discovered in 2008 in the orbit of the sunlike star WASP-13. The planet has a mass of nearly half that of Jupiter, but a radius five-quarters of the size of Jupiter. This low relative mass might be caused by a core that is of low mass or that is not present at all.

HAT-P-13c is a substellar object orbiting the star HAT-P-13 located 698 light years away from Earth in the constellation of Ursa Major. A search for transits was negative, however only 72% of the possible transit configurations could be ruled out. With a mass at least 15.2 times that of Jupiter, it may be a massive planet or a small brown dwarf. The gravitational effect of this object on the inner transiting planet HAT-P-13b may allow a precise determination of the inner planet's internal structure.

WASP-16b is an extrasolar planet that travels around its star, WASP-16, every 3.12 days. Likely a hot Jupiter. Its mass is near .855 of Jupiter, the radius is 1.008 of Jupiter. It was discovered in 2009 by a team led by T.A. Lister as part of the Wide Angle Search for Planets project. ==Characteriscics== In 2012, it was found from the Rossiter–McLaughlin effect that WASP-16b orbits its slow-rotating and likely old parent star WASP-16 in a prograde direction, with the star's rotational axis inclined to the planetary orbit by .

thumb | right OGLE-2007-BLG-368Lb is an extrasolar planet located approximately 19,230 light-years away in the constellation of Scorpius, orbiting the star OGLE-2007-BLG-368L. This planet was detected on December 8, 2009 by the gravitational microlensing by Sumi. It has mass 6.94% of Jupiter (i.e. 22 times that of Earth) and is located 3.3 AU from the star when observed. Based on those properties it would classify as a Cold Neptune. It is the second Cold Neptune to be observed, the first being OGLE-2005-BLG-169Lb. This planet is most likely be similar to Uranus and Neptune in the Solar System

MOA-2008-BLG-310Lb is an extrasolar planet which orbits probably the late K-type star MOA-2008-BLG-310L, located at least 20000 light years away in the constellation Scorpius. This planet has mass 23% of Jupiter or 77% of Saturn and orbits at 1.25 AU from the star. This planet was discovered by using the gravitational microlensing method on August 4, 2009. As it is typical for exoplanets detected by microlensing method, the orbital period and eccentricity are not determined.
