The Algol star system is known as an eclipsing binary pair, As such, one star moves in front of the other, blocking it's light. Because the pair are in line with the Earth, it has the effect that one stars seems to disappear.

See related link for an animation of the effect.

How big is Algol?

Algol is a binary star system located approximately 93 light-years away from Earth. The primary star, Algol A, is a blue-white subgiant star with around 3 times the mass of the Sun, while the secondary star, Algol B, is a smaller main sequence star. The system has a combined apparent magnitude of about 2.1, making it one of the brightest stars in the night sky.


The star Algol is better classified as a what type of star?

Algol (Demon Star) is a bright star in the constellation Perseus.Algol is actually a triple star system - Beta Persei A, B, and CBeta Persei A has a spectral type of B8 and is a blue-white giantBeta Persei B has a spectral type of K0 and is an orange subgiantSee related link for more information.


Is algol related to mira?

No, Algol and Mira are different astronomical objects. Algol is a binary star system located in the constellation Perseus, while Mira is a red giant star in the constellation Cetus. Both are variable stars, but they are not related astronomically.


Are there any planets located near the star algol?

There are no known planets located near the star Algol, which is a binary star system consisting of two stars. The distance between the two stars is relatively close, making it difficult for planets to stably orbit either of the stars.


Why Algol regularly change its brightness?

Algol is a binary star system composed of two stars orbiting each other. The dimming and brightening of Algol occur when the dimmer star passes in front of the brighter star from our point of view, resulting in an eclipse. This regular change in brightness is known as an eclipsing binary system.

How can you explain the Algol paradox?

In some binary systems, the less-massive star has become a giant, while the more-massive star is still on the main sequence. If higher-mass stars evolve faster than lower-mass stars, how do the lower-mass stars in such binaries manage to leave the main sequence first? This is called the Algol paradox, after the binary system Algol.
