Orion OB1 (Ori OB1) is a contingent group of several dozen hot giant stars of spectral types O and B in Orion. Associated are thousands of lower-mass stars, and a (smaller but significant) number of protostars. It is part of the larger Orion molecular cloud complex. Owing to its relative closeness and complexity it is the most closely studied ...
25 Orionis is the dominant member of a rich low-mass star region, [9] first identified in 2005 in a statistical analysis of 2.5 million stars. [10] It is one of several sub-associations within Orion OB1a, all thought to lie at around the same distance of 338 parsecs.
The Orion OB1 association represents different stellar populations that are superimposed along our line of sight. The oldest group with 8-10 million years is Orion OB1a, northwest of Orion's Belt, and the youngest group with less than 2 million years is Orion OB1d, which contains the Orion Nebula cluster and NGC 2024.

Eta Orionis or Algjebbah, Latinized from η Orionis, is a multiple star in the constellation Orion. It lies a little to the west of Orion's Belt between Delta Orionis and Rigel, being closer to Delta Orionis than to Rigel. It lies at a distance of around 1,000 light-years from Earth and is part of the Orion OB1 association.
Orion's Belt is a group of three bright stars in a row in the constellation Orion. Orion's Belt or the Belt of Orion may also refer to: Orion's Belt, a 1977 novel; Orion's Belt, a 1985 film based on the novel; Belt of Orion Award, an award for excellence of the Air Cadet League of Canada; Orion OB1a or Belt of Orion OB association

CVSO 30 (PTFO 8-8695) is a suspected binary T Tauri star, located in constellation Orion at 1200 light years from Earth with one candidate planet called CVSO 30 c. The candidate planet is a gas giant. The star is named after the CIDA Variability Survey of Orion (CVSO) [4] and the Palomar Transient Factory (PTF) and is within the 25 Ori group. [5]
