The dust spectra can then be compared with those from observations of other stars, giving new clues as to where Earth-like planets can be found in the universe. The dust counter is named for Venetia Burney , who first suggested the name "Pluto" at the age of 11.
If this system forms planets, the inner planets will likely orbit in the opposite direction to the outer planets. [35] WASP-17b was the first exoplanet that was discovered to be orbiting its star opposite to the direction the star is rotating. [36] A second such planet was announced just a day later: HAT-P-7b. [37]
Each night the planet appeared to lag a little behind the stars, in what is called prograde motion. Near opposition, the planet would appear to reverse and move through the night sky faster than the stars for a time in retrograde motion before reversing again and resuming prograde. Epicyclic theory, in part, sought to explain this behavior.
A “planet parade” of six planets will soon appear to align in the sky near dawn, but only three will be visible to the naked eye. Here’s how to view the event.
The team released a paper of their findings dated 27 April 2007, published in the July 2007 journal Astronomy & Astrophysics. [1] At the time of discovery, it was reported to be the first potentially Earth-like planet in the habitable zone of its star [5] [6] and the smallest-known exoplanet around a main-sequence star, but on 21 April 2009, another planet orbiting Gliese 581, Gliese 581e ...

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 ...
