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.
If the Sun–Neptune distance is scaled to 100 metres (330 ft), then the Sun would be about 3 cm (1.2 in) in diameter (roughly two-thirds the diameter of a golf ball), the giant planets would be all smaller than about 3 mm (0.12 in), and Earth's diameter along with that of the other terrestrial planets would be smaller than a flea (0.3 mm or 0. ...
Planet Taphao Thong was discovered in 1996 and was one of the first exoplanets to be discovered. [48] The planet was the first long-period extrasolar planet discovered. The other planets were discovered later. [49] Nu 2 Lupi: Lupus: 15 h 21 m 49.57 s: −48° 19′ 01.1″ 5.65: 47: G2V: 0.906: 5664: 10.36: 3: One of the oldest stars in the ...
The eight planets of the Solar System with size to scale (up to down, left to right): Saturn, Jupiter, Uranus, Neptune (outer planets), Earth, Venus, Mars, and Mercury (inner planets) A planet is a large, rounded astronomical body that is generally required to be in orbit around a star, stellar remnant, or brown dwarf, and is not one itself.

For the first time ever, scientists announced this week that they have detected an atmosphere around a planet roughly the same size as Earth outside of our solar system, a key factor in the search ...
Comet Lovejoy and Jupiter, a giant gas planet The Sun ; Sirius A with Sirius B, a white dwarf ; the Crab Nebula , a remnant supernova A black hole (artist concept); Vela Pulsar , a rotating neutron star
Also known as a binary planet. Two planetary-mass objects orbiting each other. OGLE-2017-BLG-0380Lb [2] Eccentric Jupiter: A gas giant that orbits its star in an eccentric orbit. HD 80606 b, HD 20782 b: Exoplanet: A planet that does not orbit the Sun, but a different star, a stellar remnant, or a brown dwarf. Proxima Centauri b, 51 Pegasi b ...
Mars and Jupiter are cozying up in the night sky for their closest rendezvous this decade. In reality, our solar system’s biggest planet and its dimmer, reddish neighbor will be more than 350 ...
