HD 292249 Facts

Information on HD 292249

HD 292249 is one of four possible locations of the source of Oumuamua, the inter-solar system visitor that was discovered in 2017. Another possible location is HIP 3575, (Gaia DR2 2525688198820543360) a red dwarf star located in Tucana. The other stars are known as Gaia DR2 2502921019565490176 (= home-3) and Gaia DR2 3666992950762141312 (= home-4). Ref: Arxiv

HD 292249's Alternative Names

The Id of the star in the Henry Draper catalogue is HD292249.

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

Location of HD 292249

The location of the 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 HD 292249, the location is 06 44 22.8382572761 and -01 51 11.477909454 .

Radial Velocity and Proper Motion of HD 292249

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 -70.91 milliarcseconds/year towards the north and -5.33 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 33.12 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 HD 292249

HD 292249 Colour and Temperature

HD 292249 has a spectral type of G5 E. This means the star is a white to yellow star.

Distance to HD 292249

The Parallax of the star is given as 24.12 which gives a calculated distance to HD 292249 of 135.20 light years from the Earth or 41.45 parsecs. It would take a spaceship travelling at the speed of light, 135.20 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 8,549,616.64 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.
