Information on HE 0437-5439

This star is a relatively new star, only a mere 30 million years old, much more recent in birth than the extinction of the Dinosaurs. It is of interest to many astronomers because it is moving fast out of the Milky Way Galaxy and will beknown eventually as a Rogue Star. A Rogue Star is a star that isn`t in any galaxy, also known as an intergalactic star.

It was first discovered in 2005 and its proper motion was revealed in 2010. It is believed that the star was part of a multiple star system which got to close to the galactic centre, one of the stars got sucked into the centre causing the other two to merge and begins its journey outwards. Its speed has been measured at 1,600,000 miles per hour (2,600,000 km/h) which is three times faster than the Sun orbiting the galactic centre. ref:E.S.O.

Location of HE 0437-5439

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 star is compared to the celestial equator and is expressed in degrees. For HE 0437-5439, the location is 04h 38m 12.772 and -54 ° 33` 86 .

Physical Properties (Colour) of HE 0437-5439

HE 0437-5439 has a spectral type of BV. This means the star is a blue main sequence dwarf star.

HE 0437-5439 Apparent and Absolute Magnitudes

HE 0437-5439 has an apparent magnitude of 16.30 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.
