Andromeda VIII

Andromeda VIII short and And VIII is a spheroidal dwarf galaxy ( dSph ) in the constellation of Andromeda. The galaxy is about 2.7 million light years away from our solar system. Andromeda VIII is a member of the Local Group, and is a satellite of the Andromeda Galaxy M31.

Properties

Discovered in August of 2003, the galaxy Andromeda VIII remained undetected due to their strong diffuse nature long time. Ultimately betrayed the redshift of some stars in the foreground of the Andromeda galaxy its existence, which significantly differed from that of M31.

The dwarf galaxy contains between five to twelve planetary nebulae and one to three globular clusters, as well as a non-negligible amount of neutral hydrogen gas of about 4 × 105 Mʘ.

Due to the large differences in the radial velocity of both M31 and also M32, it is virtually impossible that And VIII is physically associated with them, proves rather that it is a separate galaxy with low surface brightness in this dwarf galaxy. The extreme elongation of the dwarf galaxy is due to tidally forth mediated by the Andromeda Galaxy, which threaten to tear the dwarf. The tide can even be a significant number of stars from Andromeda VIII already escape and form along the orbit a star power.

Until at least 2006, the actual status of And VIII Galaxy unsecured ( Merrett et al. 2006).
