What else can I help you with?
What are two factors that determine the brightness of a star?
distance from the sun and the age of the star
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.
What three things affect the apparent magnitude of a star?
1: The size of the planet.2: The planet's distance from the Sun.3: The "albedo" of the planet (the percentage of the Sun's light it reflects).If you mean how bright the planet appears to us on Earth, then the distance from Earth is obviously very important.
A star's absolute magnitude is its apparent brightness as seen from?
A star's absolute magnitude is its brightness as seen from a standard distance of 32.6 light-years away. It accounts for the intrinsic brightness of the star without regard to its distance from Earth.
A sun seen from a great distance?
A sun seen from a great distance appears as a bright point of light in the sky, much like a star. Its size and brightness would diminish as the distance increases, but it would still stand out due to its luminosity, even at a great distance.
How many times is the star polaris brighter than the sun?
Polaris, also known as the North Star, is approximately 2,500 times brighter than the Sun. This brightness is measured in terms of absolute magnitude, where Polaris has an absolute magnitude of about -3.6, compared to the Sun's absolute magnitude of about +4.8. However, the apparent brightness of stars can vary based on their distance from Earth.
How does the sun rank its terms of size and brightness in your galaxy?
dwarf star
What is the distance from the sun to the star vega?
The distance from the sun to the star Vega is roughly 25.3 light years.
What could you say about a star whose absolute visual magnitude was 0 and whose visual magnitude was also 0?
That means that by definition, the star is at the standard distance of 10 parsecs.That means that by definition, the star is at the standard distance of 10 parsecs.That means that by definition, the star is at the standard distance of 10 parsecs.That means that by definition, the star is at the standard distance of 10 parsecs.
Why doesn't apparent magnitude actually measure the brightness of the star?
The apparent magnitude of the Sun is listed as -26.74. I want to know what is the formula used to compute this? How is this figure of -26.74 arrived at? Can this formula be employed for calculating the apparent magnitudes of stars of different spectral types too?
The actual brightness of the star is what?
a star is made up of burning gases which makes it a luminous body. the sun is the only star in the solar system. the brightest star except the sun is sirius
