LHS 288 Facts

LHS 288's Alternative Names

The Gliese ID of the star is GJ 3618. 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.

Location of LHS 288

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 LHS 288, the location is 10 44 21.2334129761 and -61 12 35.263329881 .

Proper Motion of LHS 288

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 1,610.34 milliarcseconds/year towards the north and -346.44 milliarcseconds/year east if we saw them in the horizon. . 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 LHS 288

LHS 288 Colour and Temperature

LHS 288 has a spectral type of M5.5V C. This means the star is a red main sequence star.

Distance to LHS 288

The Parallax of the star is given as 206.82 which gives a calculated distance to LHS 288 of 15.77 light years from the Earth or 4.84 parsecs. It is about 92,705,922,135,105.37 miles from Earth.

The star is roughly 998,314.71 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.

Time to Travel to LHS 288

A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).

If you were to drive there at about 120 m.p.h. in a car with an infinity engine so you didn't have to pull over for petrol, it would take you 772,549,351,125.88 hours or 88,190,565.20 years.

At the time of writing, the fastest probe so far created is the New Horizon probe which is travelling at a speed of 33,000 m.p.h. If the probe was travelling to LHS 288 then it would take 2,809,270,367.73 hours / 320,692.96 years to get there. Speed Ref: N.A.S.A.

It would to take a spaceship journey travelling at the speed of light, 15.77 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.
