regulus apparent magnitude

Regulus, also known as Alpha Leonis, is the brightest star in the constellation Leo and the 21st brightest star in the night sky.

Regulus D is a 12th magnitude companion at 212", [27] but is an unrelated background object.
The 2018 Gaia data release 2 revealed it to be a background object, not physically related to the Regulus system. That means it can be seen from the entire Earth.

regulus, with the most positive apparent magnitude, appears the faintest in our sky which star has the highest surface temperature? It is slightly fainter than Antares in the constellation Scorpius, Spica in Virgo and Pollux in Gemini, but outshines Deneb in Cygnus, Mimosa in Crux and Regulus in Leo. Alpha Leonis is not really a single star, but a multiple star system. See more. Regulus definition, a first magnitude star in the constellation Leo. Regulus is the only 1st magnitude star to sit almost squarely on the ecliptic, which marks the path of the sun, moon and planets across our sky.

A faint star will have a high number.
Regulus C has an apparent magnitude of 13.50 which is how bright we see the star from Earth. spica, of spectral type B1 (closest to O in OBAFGKM), has the highest surface temperature It has an apparent magnitude of 1.35 and lies at a distance of 79.3 light years, or 24.3 parsecs, from Earth. With an apparent magnitude of 1.16, it is the brightest star in Piscis Austrinus and the 18th brightest star in the sky. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. [28] Regulus A is a binary star consisting of a blue-white main sequence star of spectral type B7V, which is orbited by a star of at least 0.3 solar masses, which is probably a white dwarf. The 2018 Gaia data release 2 revealed it to be a background object, not physically related to the Regulus system. Regulus D is a 12th magnitude star located at a separation of 212 arcseconds. Apparent Magnitude is also known as Visual Magnitude. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. Denebola / d ə ˈ n ɛ b ə l ə /, designated Beta Leonis (β Leonis, abbreviated Beta Leo, β Leo) is the second-brightest star in the zodiac constellation of Leo, although the two components of the γ Leonis double star, which are unresolved to the naked eye, have a combined magnitude brighter than it.
