What is the BeiDou-2 constellation?
Beidou-2 (2004-): Developed between 2004 and 2012, the following Beidou constellation was a more advanced satnav constellation aimed at serving the Asian-Pacific region. Interestingly, it differs from other GNSS constellations by combining MEO satellites with GEO and IGSO satellites (respectively 4, 5, and 5 satellites).
Which constellation for beidou?
Beidou ( Chinese: 北斗) is the Chinese name for the constellation known as the Big Dipper , also known in Chinese as 北斗七星 Běidǒu Qīxīng, lit. “Seven Stars of the Big Dipper.” Polaris, the North Star, is within this constellation and is known to be used by sailors for navigation at sea.
When will China’s BeiDou-3 constellation be completed?
While the space segment of the Beidou-3 constellation (ie. the satellites) were completed in June 2020 , these more sophisticated GNSS augmentation services are still in the deployment phase and should be completed by 2025 based on various reports by China’s Satellite Navigation Office (CSNO)  .
The second generation of the system, officially called the Bei. Dou Navigation Satellite System (BDS) and also known as COMPASS or Bei. Dou-2, became operational in China in December 2011 with a partial constellation of 10 satellites in orbit. Since December 2012, it has been offering services to customers in the Asia-Pacific region.
This begs the inquiry “What does BeiDou stand for?”
The official English name of the system is Bei. Dou Navigation Satellite System. It is named after the Big Dipper asterism, which is known in Chinese as Běidǒu ( Chinese: 北斗 ).

Where is the star Betelgeuse located?
Betelgeuse is the tenth brightest star in the night sky and the second brightest star found in the constellation Orion, located at the eastern shoulder of the hunter . At near-infrared wavelengths, however, the rust-colored star is the brightest star in the sky.
What is the brightness of Betelgeuse?
Because it varies in magnitude, Betelgeuse occasionally surpasses Procyon in Canis Minor in brightness and becomes the seventh brightest star in the sky. When at its brightest, Betelgeuse outshines Rigel, the brightest star in Orion, and becomes the sixth brightest star in the sky.
The Chinese know Betelgeuse as 参宿四 ( Shēnxiùsì ), or the Fourth Star of the Constellation of Three Stars. The constellation originally included only the three stars of Orion’s Belt ( Alnitak, Alnilam and Mintaka ), but was later expanded to include other bright stars of Orion.
Our chosen answer is Betelgeuse is surrounded by an intricate envelope about 250 times the star’s size, composed of material lost from the star . The vast dust and gas shells extend almost 20,000 astronomical units away from the star.
