Map showing the Orion OB1 association, which contains the blue supergiants of Orion's Belt and the Orion Nebula. Betelgeuse is believed to be a runaway star that was ejected from the Orion OB1 association. The kinematics of Betelgeuse are complex. The age of Class M supergiants with an initial mass of 20 M ☉ is roughly 10 million years.
Orion's Belt or The Belt of Orion is an asterism within the constellation. It consists of the three bright stars Zeta (Alnitak), Epsilon (Alnilam), and Delta (Mintaka). Alnitak is around 800 light years away from earth and is 100,000 times more luminous than the Sun and shines with magnitude 1.8; much of its radiation is in the ultraviolet range, which the human eye cannot see.

Jun 1, 2018 · Betelgeuse is a star in a hurry — travelling through space at about 67,000 mph (30 km/s) relative to the surrounding interstellar medium. For comparison, the Apollo Command Modules returning astronauts from the Moon reached speeds of around 25,000 miles per hour, and the New Horizons probe exploring the Kuiper Belt travels around 36,000 miles per hour.
