HIP 13044 b is a Jupiter-like extrasolar planet orbiting the old and metal-poor red giant star HIP 13044, which is situated approximately 2,000 light years away from the Earth in the constellation Fornax. Its discovery was announced on November 18, 2010 after observations using the FEROS spectrograph at La Silla Observatory. According to evolutionary theories, HIP 13044 was formed in another galaxy, and became part of the Milky Way when the star`s parent galaxy was absorbed by our own between six and nine billion years ago, the remnants of the galaxy forming the Helmi stream. The planet has a very irregular orbit that is probably derived from the gravitational instabilities associated with HIP 13044`s transition into the red giant phase of its lifetime. At the time of its discovery, HIP 13044 b orbited what was noted as the oldest and most metal-poor star yet discovered.
