It is also a common practice in modern astronomy, when locating objects in the sky, to indicate which constellation their coordinates place them in proximity to, thus conveying a rough idea of where they can be found. Alnitak is around 800 light years away from earth and is 100,000 times more luminous than the ; much of its radiation is in the ultraviolet range, which the human eye cannot see. Hence, any given point in a celestial coordinate system can unambiguously be assigned to a constellation. Hap is in the middle and has been shot by the hunter; its blood has dripped onto.

There are currently 16 constellations available: 5 bright, 7 dim, and 4 faint.
For many of the constellations, these dim stars fill in the fine details of the patterns, making them more recognizable. In deregulated energy markets, Constellation offers a variety of natural gas and electricity plans for small business owners who want to be empowered and more informed when making smart energy choices for your business' needs and budget. The rising constellations rotate based on the Earth's path through space, and so can be used to mark the seasons in regions when moderate weather may not convey the change between winter and spring.
