Absolute magnitude

Absolute magnitude is the measure of intrinsic brightness of a celestial object.

Apparent magnitude

The apparent magnitude (m) of a celestial object is a measure of its brightness as seen by an observer on Earth, adjusted to the value it would have in the absence of the atmosphere.

Betelgeuse

Betelgeuse, also known by its Bayer designation Alpha Orionis (shortened to α Orionis or α Ori), is the ninth-brightest star in the night sky and second-brightest in the constellation of Orion.

Epoch (astronomy)

In astronomy, an epoch is a moment in time used as a reference point for some time-varying astronomical quantity, such as the celestial coordinates or elliptical orbital elements of a celestial body, because these are subject to perturbations and vary with time.

Flare star

A flare star is a variable star that can undergo unpredictable dramatic increases in brightness for a few minutes.

Light-year

A light-year (abbreviation: ly), sometimes written light year, is a unit of length used informally to express astronomical distances.

Main sequence

In astronomy, the main sequence is a continuous and distinctive band of stars that appears on plots of stellar color versus brightness.

Minute and second of arc

A minute of arc (MOA), arcminute (arcmin) or minute arc is a unit of angular measurement equal to one-sixtieth of one degree.

Orion (constellation)

Orion is a prominent constellation located on the celestial equator and visible throughout the world.

Parsec

A parsec (symbol: pc) is a unit of length used to measure the astronomically large distances to objects outside the Solar System.

New!!: GJ 3379 and Parsec · See more »

Radial velocity

The radial velocity of an object with respect to a given point is the rate of change of the distance between the object and the point.

New!!: GJ 3379 and Radial velocity · See more »

Red dwarf

A red dwarf is a small and relatively cool star on the main sequence, either late K or M spectral type.

Star

A star is a luminous sphere of plasma held together by its own gravity.

Stellar classification

In astronomy, stellar classification is the classification of stars based on their spectral characteristics.

Sun

The Sun (in Greek: Helios, in Latin: Sol) is the star at the center of the Solar System and is by far the most important source of energy for life on Earth.
