Gliese 3128

Gliese 3128 Facts

Gliese 3128's Alternative Names

The Gliese ID of the star is GJ 3128. The star was added to the Gliese catalogue in 1970 by Richard van der Riet Woolley hence the GJ prefix rather than GL prefix.Star Names.

More details on objects' alternative names can be found at Star Names .

Location of Gliese 3128

The location of the main sequence star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. If the R.A. is positive then its eastwards. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. For Gliese 3128, the location is 02 02 16.2424149421 and +10 20 13.953769861 .

Radial Velocity and Proper Motion of Gliese 3128

Proper Motion

All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun. In the case of a star, its the galactic centre. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. Proper Motion details the movements of these stars and are measured in milliarcseconds. The star is moving -281.62 milliarcseconds/year towards the north and -673.11 milliarcseconds/year east if we saw them in the horizon.

Radial Velocity

The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is 17.00 km/s . When the value is negative then the star and the Sun are getting closer to one another, likewise, a positive number means that two stars are moving away. Its nothing to fear as the stars are so far apart, they won't collide in our life-time, if ever.

Physical Properties (Colour) of Gliese 3128

Gliese 3128 Colour and Temperature

Gliese 3128 has a spectral type of M5.5V C. This means the star is a red main sequence star.

Distance to Gliese 3128

The Parallax of the star is given as 108.53 which gives a calculated distance to Gliese 3128 of 30.05 light years from the Earth or 9.21 parsecs. It is about 20,152,029,701 miles from Earth.

The star is roughly 1,899,685.63 Astronomical Units from the Earth/Sun give or take a few. An Astronomical Unit is the distance between Earth and the Sun. The number of A.U. is the number of times that the star is from the Earth compared to the Sun.

Travel Time to Gliese 3128

The time it will take to travel to this star is dependent on how fast you are going. U.G. has done some calculations as to how long it will take going at differing speeds. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).

The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet.
