Which planet has the greatest visual magnitude?
Venus has the greatest visual magnitude when viewed from Earth.Note: one might think Jupiter would have the greatest visual magnitude, but Jupiter is quite far away from Earth, and reflects back much less sunlight than the inner planets.
What is the limiting visual apparent magnitude of a 200 inch diameter telescope?
The limiting visual apparent magnitude of a 200-inch diameter telescope is around 27-28 magnitudes. This means it can detect very faint objects in the night sky, making it a powerful tool for astronomical observations.
The apparent visual magnitude of a star is 7.3?
That object is easily visible with a pair of binoculars. A star's apparent brightness is exactly 100 times less than another star if its apparent magnitude is +5 greater. So, the star of magnitude 7.3 appears 100 times fainter than a star of magnitude 2.3. (Polaris is a bit brighter than magnitude 2.3).
How will a star bright if it was near the sun?
A star near the Sun might be brighter or dimmer, it depends on how big it is. Each star has an absolute magnitude and if you find out a star's absolute magnitude, and then subtract 31.4, that would be its visual magnitude at the Sun's distance from us.
I am given the bolometric BC equals -1.46 and the visual magnitude V equals 4.33 of a star. how do you calculate the angular diameter?
The bolometric correction allows you to convert between visual and bolometric (total) magnitude - where the bolometric magnitude includes all radiation emitted by the star, not just visible light. It has nothing to do with the angular diameter.
What is the magnitude of Altair star?
Apparent magnitude is 0.77 Absolute magnitude is 2.21Wikipedia lists its visual magnitude as 0.77.
Name for How bright a star is from the earth?
The brightness of a star is called visual magnitude. The lower the visual magnitude is the brighter the star is.
What is the magnitude of the markab?
well it depens on what magnitude? For example is it visual, apparent, or absolute?
How much brighter is a star with an apparent visual magnitude of 13.4 than a star with an apparent visual magnitude of 15.4?
A star with a visual magnitude of 13.4 is 10 times brighter than a star with a magnitude of 15.4, because each step in magnitude represents a factor of about 2.5 in brightness.
What is the brightness of the Polaris?
Visual magnitude 2.02.
Which star is brighter a star with a magnitude of 3.2 or 4.6?
A star with an apparent visual magnitude of 3.2 appears 1.4 magnitudes brighter than another one whose apparent visual magnitude is 4.6 .
How much brighter is -5 from 5?
A star or other heavenly body whose visual magnitude is -5 is 2,154.4 times as bright as another body with visual magnitude of +5.
Which planet has the greatest visual magnitude?
Venus has the greatest visual magnitude when viewed from Earth.Note: one might think Jupiter would have the greatest visual magnitude, but Jupiter is quite far away from Earth, and reflects back much less sunlight than the inner planets.
What is the sun's magnitude and distance from Earth?
The Sun has an absolute magnitude of about 4.8 and an apparent (visual) magnitude of around -26.7. It's roughly 150,000,000 km from Earth on average.
What is the limiting visual apparent magnitude of a 200 inch diameter telescope?
The limiting visual apparent magnitude of a 200-inch diameter telescope is around 27-28 magnitudes. This means it can detect very faint objects in the night sky, making it a powerful tool for astronomical observations.
What is a bright star -5 or 5?
A star with apparent visual magnitude of -5, if there were any, would appear ten magnitudes brighter than (about 2,154 times as bright as) one with apparent visual magnitude of +5.
What term is used to describe a star's brightness?
It is called Vmag. This is the visual magnitude of the object. Visual magnitude is a scale used by astronomers to measure the brightness of a star or other celestial object. Visual magnitude measures only the visible light from the object. The lower the V-MAG the brighter the star. You can go to http://seasky.org/pictures/sky7b14.html to learn more.
