What are 2 factors that cause the pattern of seasons?
1) The annual orbit of the Earth round its star, the Sun. 2) The inclination of Earth's axis of spin to the plane of the orbit.
What are the factors and prime factors of 4496?
As a product of its prime factors: 2*2*2*2*281 = 4496
What is 6 two common factors?
The factors of 2 are: 1, 2 The factors of 6 are: 1, 2, 3, 6 The common factors are: 1, 2
What are the prime factors for 2-200?
202
What are the factors and prime factors of 914?
The prime factors of 904 are: 2, 113
What two factor affect a stars apparent brightness?
Two factors that affect a star's apparent brightness are: 1.) The distance between the Earth and the star 2.) The absolute magnitude (the actual brightness) of the star Hope that helps :P
What do star's brightness depend on?
it depends upon 3 factors,1-the distance from the earth, 2-size of star and 3-age of the star.
What 3 factors affect how bright a star appears from earth?
The 3 factors that affect a star's brightness as viewed from earth, are: The star's age, distance from earth, and actual magnitude (scale a star's brightness is measured in).
Looking at the H-R diagram what 2 factors determine the brightness of a star?
The H-R diagram graphs total brightness versus surface temperature (related to color); by itself, it doesn't tell you where those two things come from.The brightness of a star depends on its mass, and on where it is in its development history.
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.
What is difference between apparent brightness and true brightness?
Apparent brightness: how bright an object - such as a star - looks to us. True brightness: how bright such an object really is. Defined as: how bright it would look at a standard distance.
Which star is brighter -2 or -3?
The way stellar magnitude works, a smaller number is associated with increased brightness. Since -3 < -2, a magnitude -3 star would be brighter than a magnitude -2 star. Each decrease in magnitude by 1 means in increase in brightness by a factor of about 2.5119. Equivalently, each decrease in magnitude by 5 means an increase in brightness by a factor of 100. Incidentally, the brightest star in the sky (Sirius) has an apparent magnitude of only about -1.5.
What affects the luminosity of stars?
There are 2 main factors: the size of the star and its surface temperature. A larger size means a larger surface area to emit light. A higher surface temperature increases the energy emitted. Seen from Earth, the brightness of a star depends on how far away the star is as well as its actual luminosity.
What is ment by magnitude?
1) in astronomy it is the degree of brightness of a star. 2) It is relative importance or significance, as in size, extent or dimensions
Compared to a magnitude 1 star a star with a magnitude of 2 is?
A magnitude 1 star is about 2.512 times brighter than a magnitude 2 star. The exact factor is the fifth root of 100 - this means that a difference of 5 magnitudes is equivalent to a brightness factor of 100.
05. What two parameters does the brightness of a star depend on?
The brightness of a star - or apparent magnitude [See related question] is how bright a star is as viewed from Earth. Therefore, if we have two stars of similar luminosity but one is twice as far away, then the further star would appear dimmer than the closer star. There are more luminous stars than our Sun but because the Sun is a lot closer, it is brighter. So the brightness of a star depends on it's luminosity and it's distance from the observer. A stars luminosity is a factor of how hot it is, and how big it is.
What two factors affect how bright a star appears in the night sky?
Two factors that affect a star's apparent brightness are: 1.) The distance between the Earth and the star 2.) The absolute magnitude (the actual brightness) of the star Hope that helps :P
