How can you find the luminosity of a main sequence star?
You can find the luminosity of a main sequence star by measuring its apparent brightness and distance from Earth. Knowing the distance allows you to calculate the star's absolute brightness. Luminosity is then determined by comparing the absolute brightness of the star to that of the Sun, which has a known luminosity.
Which type of star does the earth orbit?
main sequence
If all the main sequence stars of a star cluster are typically only one hundredth as bright as their main sequence counterparts in the Hyades Cluster than the cluster's distance?
can be estimated by comparing their apparent magnitudes. Since brightness decreases with the square of the distance from an observer, a star cluster with main sequence stars one hundredth as bright as the Hyades Cluster would be approximately ten times further away from Earth than the Hyades Cluster.
Is a dwarf star headed for earth?
No, there is no dwarf star heading for Earth. The closest star to Earth is the Sun, which is a main-sequence star. Dwarf stars are common in the universe and many are much farther away from Earth.
What kind of star is your sun?
Earth's Sun is:a G2V type star,a yellow dwarf anda main sequence star
What is earths type star?
Earth's star is what we call the Sun, and it is a main-sequence star with a G2 spectrum and an absolute magnitude of +4.7.
Is a red giant star considered to be a main sequence star?
No. Red giants are not on the main sequence.
Is vega a dwarf star?
No, Vega is not a dwarf star. It is a main sequence star, specifically a type A main sequence star. Vega is one of the brightest stars in the night sky and is located relatively close to Earth in the constellation of Lyra.
Does a red main sequence star have fusion?
A red main sequence star would be a red dwarf or a branch red giant. To be on the main sequence, you have to have hydrogen nuclear fusion.
What type of star is Merak?
Merak is a blue-white main sequence star, also known as a type A1V star. It is part of the Big Dipper (Ursa Major) constellation and is approximately 79 light-years away from Earth.
What is a stabilized star?
Main-Sequence star
What category does a star belong in Main sequence star white dwarf red giant neutron star?
None of those is a main sequence star.
