Absolute magnitude
In astronomy, absolute magnitude is a measure of the luminosity of a celestial object on an inverse logarithmic astronomical magnitude scale.
See NGC 2423-3 and Absolute magnitude
Amplitude
The amplitude of a periodic variable is a measure of its change in a single period (such as time or spatial period).
Apparent magnitude
Apparent magnitude is a measure of the brightness of a star or other astronomical object.
See NGC 2423-3 and Apparent magnitude
Astronomical unit
The astronomical unit (symbol: au, or AU) is a unit of length defined to be exactly equal to.
See NGC 2423-3 and Astronomical unit
Astronomy & Astrophysics
Astronomy & Astrophysics (A&A) is a monthly peer-reviewed scientific journal covering theoretical, observational, and instrumental astronomy and astrophysics.
See NGC 2423-3 and Astronomy & Astrophysics
Brown dwarf
Brown dwarfs are substellar objects that have more mass than the biggest gas giant planets, but less than the least massive main-sequence stars.
See NGC 2423-3 and Brown dwarf
Constellation
A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object.
See NGC 2423-3 and Constellation
Doppler spectroscopy
Doppler spectroscopy (also known as the radial-velocity method, or colloquially, the wobble method) is an indirect method for finding extrasolar planets and brown dwarfs from radial-velocity measurements via observation of Doppler shifts in the spectrum of the planet's parent star.
See NGC 2423-3 and Doppler spectroscopy
Epoch (astronomy)
In astronomy, an epoch or reference epoch is a moment in time used as a reference point for some time-varying astronomical quantity.
See NGC 2423-3 and Epoch (astronomy)
Exoplanet
An exoplanet or extrasolar planet is a planet outside the Solar System.
Extrasolar Planets Encyclopaedia
The Extrasolar Planets Encyclopaedia (also known as Encyclopaedia of exoplanetary systems and Catalogue of Exoplanets) is an astronomy website, founded in Paris, France at the Meudon Observatory by Jean Schneider in February 1995, which maintains a database of all the currently known and candidate extrasolar planets, with individual pages for each planet and a full list interactive catalog spreadsheet.

HD 69830
HD 69830 (285 G. Puppis) is a yellow dwarf star located away in the constellation of Puppis.
Jupiter
Jupiter is the fifth planet from the Sun and the largest in the Solar System.
Light-year
A light-year, alternatively spelled light year (ly or lyr), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km (Scientific notation: 9.4607304725808 × 1012 km), which is approximately 5.88 trillion mi.

Mercury (planet)
Mercury is the first planet from the Sun and the smallest in the Solar System.
See NGC 2423-3 and Mercury (planet)
Metre per second
The metre per second is the unit of both speed (a scalar quantity) and velocity (a vector quantity, which has direction and magnitude) in the International System of Units (SI), equal to the speed of a body covering a distance of one metre in a time of one second.
See NGC 2423-3 and Metre per second
Michel Mayor
Michel Gustave Édouard Mayor (born 12 January 1942) is a Swiss astrophysicist and professor emeritus at the University of Geneva's Department of Astronomy.
See NGC 2423-3 and Michel Mayor
Minimum mass
In astronomy, minimum mass is the lower-bound calculated mass of observed objects such as planets, stars and binary systems, nebulae, and black holes.
See NGC 2423-3 and Minimum mass
Neptune
Neptune is the eighth and farthest known planet from the Sun.
NGC 4349-127
NGC 4349-127 is a probable red giant star approximately 6,100 light-years away in the constellation of Crux.
See NGC 2423-3 and NGC 4349-127
Open cluster
No description.
See NGC 2423-3 and Open cluster
Orbital inclination
Orbital inclination measures the tilt of an object's orbit around a celestial body.
See NGC 2423-3 and Orbital inclination
Pluto
Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune.
PSR B1620−26
PSR B1620−26 is a binary star system located at a distance of 3,800 parsecs (12,400 light-years) in the globular cluster of Messier 4 (M4, NGC 6121) in the constellation of Scorpius.
See NGC 2423-3 and PSR B1620−26
Puppis
Puppis (meaning "poop deck") is a constellation in the southern sky.
Red giant
A red giant is a luminous giant star of low or intermediate mass (roughly 0.3–8 solar masses) in a late phase of stellar evolution.
Star
A star is a luminous spheroid of plasma held together by self-gravity.
Stellar pulsation
Stellar pulsations are caused by expansions and contractions in the outer layers as a star seeks to maintain equilibrium.
See NGC 2423-3 and Stellar pulsation
Sun
The Sun is the star at the center of the Solar System.
