What color is Algieba?
In 1782 William Herschel discovered that Algieba was a double star. He saw the two stars as white and pale red. Modern astronomers describe them as golden yellow, with little difference between their colors. Separated by approximately 2.5 arc seconds, both stars in the Algieba system are giant stars.
How did Leo get its name?
Leo is also called the lion. To the ancient Greeks and Romans the constellation represented the Nemean lion. The hero Heracles (or Hercules) killed the Nemean lion as part of a series of tasks he had to perform. The Romans gave the constellation the name Leo.

Is Castor a binary star?
Castor is three pairs of binary stars – six stars in all – in a complex dance around a common center of mass. Even a fairly small telescope will show Castor as two stars. You might glimpse a much-fainter star nearby, too; it's also part of the Castor system.

What makes Algieba so visually striking?
What makes Algieba so visually striking are its rich golden-yellow hues, indicative of its K0 and G7 spectra. Some observers note a slight greenish tinge to the companion. Do you agree?
Where is Algieba in Leo?
Algieba is easily located - it’s the brightest star (after Regulus) in the “Sickle” of Leo. The pair is marginally resolved in small-aperture telescopes with medium power.
What is the apparent magnitude of Algieba?
Algieba has an apparent magnitude of 2.01, this is a measure of the brightness of the star as seen from Earth. Apparent Magnitude is also known as Visual Magnitude. If you used the 1997 Parallax value, you would get an absolute magnitude of -0.92 If you used the 2007 Parallax value, you would get an absolute magnitude of -0.99.
What type of star is Algieba?
Algieba is a Giant Star type star. Algieba is a K0III giant star based on the spectral type that was recorded in the Hipparcos star catalogue.
How big is the Algieba star?
Algieba estimated radius has been calculated as being 22.19 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 15,438,679.86.km. If you need the diameter of the star, you just need to multiple the radius by 2. However with the 2007 release of updated Hipparcos files, the radius is now calculated at being round 22.92. The figure is derived at by using the formula from SDSS rather than peer reviewed papers. It has been known to produce widely incorrect figures.
How much does Algieba have in mass?
The Algieba's solar mass is 1.23 times that of our star, the Sun. The Sun's Mass is 1,989,100,000,000,000,000,000 billion kg. which to calculate using this website is too large. To give idea of size, the Sun is 99.86% the mass of the solar system.
How many extrasolar planets are there in Algieba?
Algieba has at least 1 Extrasolar Planets believed to be in orbit around the star.
Is Algieba a rocky planet?
Although the exoplanet that is detailed here is a gas giant, its quite possible that the star could have a rocky planet because rocky planets such as our Earth and Mars are small and not easy to spot. Whilst some rocky planets have been spot ted, small rocky planets are still to be spot ted.
When is the meteor shower in Gamma Leonids?
The Gamma Leonids Meteor Shower radiants from a point near this star. The meteor shower runs typically between Aug 14-Sept 12 with a peak date of 25th Aug..
Nomenclature
γ Leonis ( Latinised to Gamma Leonis) is the star's Bayer designation. The A and B components of the binary are often referred to as γ 1 Leonis and γ 2 Leonis respectively.
Stellar system
The bright binary system in Leo with orange-red and yellow or greenish-yellow components is visible through a modest telescope under good atmospheric conditions. To the naked eye, the Algieba system shines at mid-second magnitude, but a telescope easily splits the pair.
Variability
γ Leonis is a suspected variable star, with a visual magnitude range of 1.84 to 2.03. It is not known which of the two components is variable. In 1959, the star was mistakenly published as an eclipsing binary due to a typographical error when referring to Y Leonis.
Planetary system
On November 6, 2009, the discovery of a planetary companion around primary star γ 1 Leonis (γ Leonis A) was announced. The radial velocity measurements suggest two additional periodicities of 8.5 and 1340 days.
