He has been referred to by himself and by others as the man who "killed Pluto", [3] [4] [5] because he furthered Pluto's being downgraded to a dwarf planet in the aftermath of his discovery of Eris and several other probable trans-Neptunian dwarf planets. He is the author of How I Killed Pluto and Why It Had It Coming, published in 2010.
OGLE-2016-BLG-1190Lb is the first exoplanet discovered by microlensing with the Spitzer space telescope and the first exoplanet discovered lying near the planet/brown dwarf boundary. [1] [3] In addition, the discovery "is likely to be the first Spitzer microlensing planet in the Galactic bulge/bar," according to the initial reported study. [1]
In 2020, he discovered the ultrafaint dwarf galaxy named Pisces VII/Triangulum III [6] [7] which turned out to be a strong satellite candidate of the dwarf spiral galaxy Messier 33. [8] [9] Pisces VII is the first Local Group galaxy to be discovered by a non-professional astronomer. [10] [11] Donatiello II dwarf galaxy imaged by the Hubble ...
Kepler-1649c is an Earth-sized exoplanet, likely rocky, orbiting within the habitable zone of the red dwarf star Kepler-1649, the outermost planet of the planetary system discovered by Kepler’s space telescope. It is located about 301 light-years (92 pc) away from Earth, in the constellation of Cygnus. [3]
Host star is the brightest star with multiple known transiting Earth-size exoplanets. Another transiting planet in the system is suspected. [39] HD 101581 c: 0.0925 6.21 transit 41.7 0.740 ± 0.087 4675 ± 53 Host star is the brightest star with multiple known transiting Earth-size exoplanets. Another transiting planet in the system is ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
OGLE-2005-BLG-390Lb (known sometimes as Hoth by NASA [1]) is a super-Earth ice exoplanet orbiting OGLE-2005-BLG-390L, a star 21,500 ± 3,300 light-years (6,600 ± 1,000 parsecs) from Earth near the center of the Milky Way, making it one of the most distant planets known.
Kepler-37b is an exoplanet orbiting the star Kepler-37 in the constellation Lyra. [3] As of February 2013, it is the smallest planet discovered around a main-sequence star, with a radius slightly greater than that of the Moon and slightly smaller than that of Mercury. [4]
