This designation doesn't appear in the SIMBAD database, and more modern naming conventions use a separated lettering system where lower-case letters to refer to planets and upper-case letters to designate stars (e.g. Gliese 667 Cc is the 'c' planet orbiting Gliese 667C, which is the 'C' star of a triple system), making PSR B1620-26 b the ...
Motion interpolation of seven images of the HR 8799 system taken from the W. M. Keck Observatory over seven years, featuring four exoplanets. This is a list of extrasolar planets that have been directly observed, sorted by observed separations. This method works best for young planets that emit infrared light and are far from the glare of the star.
The Family Portrait, or sometimes Portrait of the Planets, is an image of the Solar System acquired by Voyager 1 on February 14, 1990, from a distance of approximately 6 billion km (40 AU; 3.7 billion mi) from Earth. It features individual frames of six planets and a partial background indicating their relative positions.
At the time of discovery, with 5.5 Earth masses, the planet was less massive than the previous candidate for lowest-mass exoplanet around a main-sequence star, the 7.5 Earth mass Gliese 876 d. Since 2013, many Earth-sized or smaller planets around main-sequence stars have been detected by the Kepler spacecraft and others.

Space junk has filled up so much of Earth's orbit that it's endangering satellites and astronauts.. The company Kayhan Space issues roughly 1,000 space-collision warnings per day. Earth-orbit ...
GJ 1214 b may be cooler than any other known transiting planet prior to the discovery of Kepler-16b in 2011 by the Kepler mission. Its equilibrium temperature is believed to be in the range of 393–555 K (120–282 °C; 248–539 °F), depending on how much of the star's radiation is reflected into space .
Counter-Earth, a planet situated on the other side of the Sun from that of the Earth. Fifth planet (hypothetical), historical speculation about a planet between the orbits of Mars and Jupiter. Phaeton, a planet situated between the orbits of Mars and Jupiter whose destruction supposedly led to the formation of the asteroid belt. This hypothesis ...
