Some 3,000 light years away from Earth, researchers believe they have found an Earth-size exoplanet orbiting a sun-like star. The star is known as Kepler-160, and it was observed during NASA's. This is an artist's illustration of a Neptune-type exoplanet in the icy outer reaches of its star system. It could look something like a large, newly discovered gas giant that takes about 20 years. Many exoplanets have been found around these types of stars. A lingering question in exoplanet research has been whether they are habitable, since red dwarfs are more active than our sun and flare. K-type stars are even better than G-type for finding potentially habitable exoplanets, says Caballero. K-type stars last a bit longer than the Sun and they emit less radiation as x-rays M-to-K is a Doppler survey for exoplanets orbiting early M through late K type stars. These stars are smaller and lower in mass than our Sun. Low mass stars tend to be under-represented on current Doppler surveys because they are intrinsically faint and therefore large telescopes are required to pick up a strong enough signal

Fomalhaut b was thought to be one of the few exoplanets photographed so far, but new observations from the Hubble Space Telescope show it's really an expanding dust cloud The PHL's Exoplanets Catalog (PHL-EC) contains observed and modeled parameters for all currently confirmed exoplanets derived from the NASA Exoplanet Archive, including those potentially habitable.The main difference between PHL-EC and other exoplanets databases is that it contains estimated parameters, habitability assessments, and planetary classifications The exoplanet Proxima b, as shown in this artist's illustration, is thought to be inhospitable to the most common type of planet is likely rocky, Earth-sized or smaller, and orbits around red. How to Search for Exoplanets. Even through a powerful ground- or space-based telescope, stars look like tiny points of light. Planets are even tinier and are very difficult to spot next to their bright host stars. Therefore, scientists rely on indirect methods, like looking at the stars themselves for signs that planets might be orbiting them The study of exoplanets is a relatively new field of astronomy. There are four main methods used by astronomers to discover new exoplanets: direct imaging, the radial velocity method, astrometry and gravitational microlensing

51 Pegasi b - the exoplanet discovered by Mayor and Queloz - is a Jupiter-mass planet that orbits close to its star, which results in a relatively large radial velocity signal. This type of planet, a gas giant orbiting very close to its parent star and known as a hot Jupiter, came as a complete surprise when discovered since theories of planet formation stated that such a planet could not. K-type dwarf stars are dimmer than the Sun but brighter than the faintest stars. These stars live a very long time -- 17 billion to 70 billion years, compared to 10 billion years for the Sun. MIT researchers have discovered four new exoplanets orbiting a sun-like star just over 200 light-years from Earth. Because of the diversity of these planets and brightness of their star, this system could be an ideal target for atmospheric characterization with NASA's upcoming James Webb Space Telescope Exoplanets of Cervantes.ogv 28 s, 640 × 480; 5.88 MB Extrasolar planet NASA2 bn.jpg 720 × 486; 40 KB First ever image of a multi-planet system around a Sun-like star.tif 990 × 990; 906 K When it comes to detecting exoplanets, there are several techniques available at the disposal of the exoplanet hunter.
