What is the dimmest star in the Ophiuchus constellation?
Beta and Alpha Herculis are both 2nd Magnitude (2.78) stars
What is brighter a second or a third magnitude star?
2nd magnitude is brighter than 3rd. 6th magnitude is the dimmest that can be seen with the naked eye; many more can be seen in binoculars, telescopes etc.
What is the dimmest planet?
Pluto
What things must an astronomer measure to calculate a star's absolute brightness?
Telescopes, combined with spectroscopy are used for the colors. The apparent brightness can be measured using a telescope with a special "CCD camera". To measure the "real" brightness ("absolute magnitude") you also need to be able to work out the distance to the star.
What is the dimmest star in the Phoenix constellation?
Kappa
What is the absolute magnitude of the dimmest star seen by eye?
6
A measure of a stars brightness is called its?
Magnitude. First magnitude descibes many bright stars, and a span of five magnitudes represents a difference of a hundred times in the star's brightness. The dimmest stars seen by a perfect human eye in perfect conditions is 6th magnitude.
What star looks dimmest from earth?
What star even tho this star has an absolute magnitude greater than that of Sirius it looks dimmer from earth since it's 100 times farther away

Which stars always have large positive absolute magnitude?
Does it mean that the star is a main sequesnce star? ( . Y . ) The above isn't true. A star can be a blue supergiant and be on the main sequence but still not be even visible to us, therefore the apparent and absolute magnitude wouldn't be the same. But to answer your question, I don't think it has a name, it just means that you are seeing the star's absolute and apparent magnitude at the same time, so if you placed the star at 32.6 light years away(the absolute magnitude scale)then the star would not appear to change in brightness
What are the three brightnesses of the stars?
I think you are referring to what astronomers call magnitude, which is defined in several different ways. Apparent magnitude is how bright a star looks compared to others. The dimmest stars we can see with the naked eye in good conditions are magnitude 6, and the brightest ones are about 1. Really bright objects like some of the planets have negative magnitude. Absolute magnitude is a way to compare how bright stars really are, because the apparent magnitude is affected by their distance from us. It's the magnitude the star would have if it were exactly ten parsecs away. Bolometric magnitude is more complex, but is an attempt to quantify the star's luminosity over all wavelengths, not just those we can see.

Which is brighter alpha ursae majoris or epsilon ursae majoris?
Alpha Ursae Majoris is brighter. It has a magnitude of 1.81 whereas, Epsilon Ursae Majoris has a magnitude of 1.76. The greek letter A (alpha) comes before the Greek letter E (epsilon) in the Greek alphabet. Astronomers named stars according to their brightness. Starting with 'A' (alpha) being the brightest and (Omega) being the dimmest.
