These conditions, along with the tilt and position of the Earth in its orbit, make observing the summer sky a little more difficult. Meanwhile, no star is. 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. Rudra, the Rigvedic form of Shiva, is the presiding deity of Ardra nakshatra (Betelgeuse) of Hindu astrology.[37]. A) there is a lunar eclipse every 6 months. B) first quarter.
