Spica, a binary star system consisting of a blue giant and a supergiant, is expected to spend around 20 to 30 million years on the main sequence. Its high mass and luminosity mean it evolves rapidly compared to lower-mass stars, which can spend billions of years in this phase. After its main sequence phase, Spica will quickly transition to the next stages of stellar evolution, likely becoming a red supergiant.
What else can I help you with?
How long will Spica stay on the main sequence?
Spica is a dual star system, with the two members too close for resolution by the best telescopes. The larger, primary star is a blue-white giant, and does have the potential to end it's life as a supernova. The primary is not a main sequence star. The secondary, about 70% the size of the primary, is a main sequence star, also blue white.
Which is hotter spica or vega?
Sun
What is the size of the star Spica?
Spica is a binary star system located in the constellation Virgo. The primary star, Spica A, is a blue giant with a diameter of about 7.5 times that of the Sun, while the secondary star, Spica B, is a main-sequence star.
Is spica a supergiant?
No, Spica is not classified as a supergiant; it is a binary star system that primarily consists of a spectral type B main-sequence star. It is one of the brightest stars in the constellation Virgo and is often referred to as a blue giant due to its significant size and luminosity, but it does not reach the scale of a supergiant. Supergiants are typically much larger and more luminous than main-sequence stars like Spica.
What class type of star is spica?
Spica is a binary star system consisting of two massive stars. The primary star in the system is a blue subgiant star, while the secondary star is a slightly smaller blue main-sequence star. Both stars are hot and luminous.

How long does an average star spend as a hydrogen- burning main sequence star?
Ten billion years
What star is brighter spica or tau ceti?
Spica is significantly brighter than Tau Ceti. Spica, located in the constellation Virgo, is a blue giant star with an apparent magnitude of about 1.04, making it one of the brightest stars in the night sky. In contrast, Tau Ceti, a G-type main-sequence star in the constellation Cetus, has an apparent magnitude of approximately 3.5, making it much fainter than Spica. Therefore, Spica outshines Tau Ceti by a considerable margin.
Where does a star spend most of its life on an hr diagram?
On the main sequence.
What state do stars spend most of their life cycle?
The main sequence.
Will a star spend most of its life as a protostar?
No, it will spend most of it's life as a main sequence star.
What class type of star is spica?
Spica is a binary star system consisting of two massive stars. The primary star in the system is a blue subgiant star, while the secondary star is a slightly smaller blue main-sequence star. Both stars are hot and luminous.
Where does a star spend most of its lifetime on the h-r diagram?
On the main sequence.
What are the spectral classes of spica?
Spica is a binary star system whose primary star is classified as a blue-white giant of spectral type B1 III-IV. The secondary star is a blue-white main sequence star of spectral type B2 V.
