20 Canum Venaticorum/AO Canum Venaticorum has an absolute magnitude of -0.02
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
A measurement that has magnitude and direction. The magnitude is equal to the absolute value of the vector measurement. For example, Velocity is a vector measurement. A velocity of -20 miles per 1 second would suggest moving away from the origin point in a two-dimensional measurement at a rate of 20 miles per 1 second. The absolute value of this would be 20 miles per 1 second, which would also be the speed. Therefore, speed is the magnitude of Velocity. Subsequently, any measurement that has a magnitude, but no direction, is not a Vector measurement, but rather a scalar measurement. Some examples of vector measurements would be Displacement, Velocity, and Acceleration.
The apparent magnitude of an RR Lyrae star at a distance of 10 parsecs would be 0, given its absolute magnitude of 0. To find the distance at which it would appear as faint as 20th magnitude, we would use the distance modulus formula, which results in a distance of 10,000 parsecs or 32,600 light-years.
There are a few ways to define "opposite." It could be -20 or 1/20. The absolute value of 20 is 20.
I beileive that the absolute value of -20 is 20 because if you do the absolute value it seems to turn out as the positive form of itself in other words, if you take -10 and find the absolute value, it is 10 and if you take 60 and find the absolute value it equals 60
