Nearest F-type main sequence star with a multiplanetary system. Second-brightest star in the night sky with a multiplanetary system after 7 Canis Majoris. All exoplanets orbit around star A in the binary system. 47 Ursae Majoris: Ursa Major: 10 h 59 m 27.97 s +40° 25′ 48.9″ 5.10: 46: G0V: 1.029: 5892: 7.434: 3
The Regulus system as a whole is the twenty-first brightest star in the night sky with an apparent magnitude of +1.35. The light output is dominated by Regulus A. Regulus B, if seen in isolation, would be a binocular object of magnitude +8.1, and its companion, Regulus C, the faintest of the three stars that has been directly observed, would ...
TOI-1338 is a binary star system located in the constellation Pictor, about 1,320 light-years from Earth. It is orbited by two known circumbinary planets , TOI-1338 b , discovered by the Transiting Exoplanet Survey Satellite (TESS) [ 2 ] and BEBOP-1c, discovered by the Binaries Escorted By Orbiting Planets project.
These alignments have different names depending on the number of stars visible. Three planets constitutes a mini alignment. Four planets are a small alignment, which we saw during April 8’s eclipse.
The planets Venus, left, and Jupiter, right, with three of its moons visible, appear close to each other in the sky above tree branches after dusk Wednesday, July 1, 2015, in Tacoma, Wash.
The wind is leaving the system with a velocity of 2,000 km s −1 or more. [5] The secondary, β Crucis B, may be a main sequence star with a stellar class of B2. [6] In 2007, a third companion was announced, which may be a low mass, pre-main sequence star. The X-ray emission from this star was detected using the Chandra X-ray Observatory.
The Kepler-444 system consists of the planet hosting primary and a pair of M-dwarf stars. The M-dwarfs orbit each other at a distance of less than 0.3 AU while the pair orbits the primary in a highly eccentric 324-year orbit. The pair comes within 23.55 AU of the primary potentially truncating the protoplanetary disk from which the planets ...
A recently discovered comet, named C/2023 A3 Tsuchinshan–ATLAS, makes its closest approach of Earth on Saturday. The comet’s next appearance may be in 80,000 years.
