Extragalactic planet This suspected planet is the first announced in the Andromeda Galaxy. A population of unbound planets between stars, with masses ranging from Lunar to Jovian masses, have been indirectly detected, for the first time, by astrophysicists from the University of Oklahoma, in the lensing galaxy that lenses quasar RX J1131-1231 by microlensing. Extragalactic planet An extragalactic planet, also known as an extragalactic exoplanet, is a star-bound planet, or rogue planet, located outside of the Milky Way galaxy. Due to the huge distances to such worlds, they would be very hard to detect directly. However, indirect evidence suggests that such planets
NASA/IPAC Extragalactic Database entered to the extent possible, and some basic data collected. Bibliographic references relevant to individual objects have been compiled, and abstracts of extragalactic interest are kept on line. Detailed and referenced photometry, position, and redshift data, have been taken from large compilations and from the literature. NED also includes images from 2MASS, from the literature, and from the Digitized Sky Survey. As of March 2014, NED contains 206 million distinct astronomical objects with 232 million cross-identifications across multiple wavelengths, with redshift measurements for 5 million objects, 1.9 billion photometric data points, 609 million diameter measurements, 71 thousand redshift-independent distances for
