NGC 2318 Galaxy Facts
NGC 2318 is a Lenticular Galaxy located in the constellation of Canis Major in the southern hemisphere. NGC 2318 is called NGC 2318 in the New General Catalogue (NGC). This catalogue is a list of deep space objects compiled by John Louis Emil Dreyer in 1888 to update John Herschel's earlier work. NGC 2318 is not a Messier Object and doesn't have a Messier Number. The galaxy is separate and distinct, not in Milky Way galaxy or The Solar System.
Nothing indicates Exoplanets with or without Alien life forms orbiting any of the many stars the galaxy has. No one has ever travelled to or sent a probe to NGC 2318, as the galaxy is too far away for current technology. No one will probably ever visit the galaxy unless they could create a Wormhole, given the distance involved.
When we observe the NGC 2318, we are not looking at it as it currently appears but as it used to appear millions or billions of years ago, given how long light to reach us from there.
NGC 2318 Location
NGC 2318's location is 06 59 25.0 (R.A.) and -13 49 19 (Dec.). They are celestial equivalents of Longitude and Latitude. The right ascension (longitude) is the angular distance of an object along the celestial equator from the March Equinox. As a rough guide, the March Equinox is located in the constellation of Pisces. If the number is negative, it is "west" of the March Equinox.
The declination (latitude) is the lenticular galaxy's angle from the celestial equator. A negative value indicates it is in the southern hemisphere.
Based on the location of Canis Major, NGC 2318 can be located in the southern hemisphere of the celestial sky. The celestial hemisphere is equivalent to the hemispheres on Earth. NGC 2318 is south of the Ecliptic. The Ecliptic is the path the Earth takes as it orbits the Sun. As the Earth is titled, we have Celestial and Ecliptic hemispheres.
Attributes of NGC 2318
Radial Velocity
Radial velocity is the speed at which an object moves away/towards the Sun. For NGC 2318, the radial velocity is 0,008.27 km/s. When the value is negative, the deep space object and the Sun are getting closer. Likewise, a positive number means that the two things are moving away.
NGC 2318 Angular Size
The Angular Size is the size given as arc minutes, which can be roughly turned into light years if you know the distance to the lenticular galaxy. Parsecs, Light Years, and Megaparsecs can be used to measure the distance. The formula is Distance * Tan ((MA/60)/(180/Pi)) MA is the Major Axis value. It probably won't give you a peer-reviewed size, but it'll give you an idea of how big it is.
- 20.6 is the major axis of the object, the length.
- 20.6 is the minor axis of the object, the width.
- (Opt) indicates quality, with A being the best quality and E being the worst.
