Once you have spotted Orion, spotting other constellations should be easy. The dimmest star that a person can see on a clear night with their naked eye is 6.0 magnitude based on the table in the reference. The faint star has an apparent magnitude of 6. The dimmest star you can see in Orion with the naked eye is HD 44497. The difference between the magnitudes is that absolute magnitude is the object from 10 Parsecs or 32.6 light-years away from the observer, whereas apparent is from Earth. The star has an apparent magnitude of 0.18 but an absolute magnitude of -6.93. Alpha stars tend to be the brightest in the constellation. The star is designated as Beta Orionis rather than Alpha designation. The brightest star in Orion is Rigel, about 862.87 light-years from the Sun. The most distant figure is derived from the 1997 or 2007 Hipparcos star catalogue parallax figure and has been known to produce wrong distances. The furthest star I have data for and can be located in Orion is HIP 27033, 326,163.30 light-years away from the Sun. The nearest star to the Earth with an exoplanet is HIP 22627, about 40.08 light-years. The nearest star to Earth that is located in the constellation of Orion is Gliese 205, about 18.45 light-years from the Earth. If you know of a star that is nearer or further, do let me know in the comments, and I'll add it to the site. The caveat of these stars is that they are catalogued on this site. The stars mentioned are from the Hipparcos catalogue or have been added because of their special status. The following neighbouring constellations surrounds Orion :. This site covers nineteen non-Messier deep space objects, and the list is below. The current biggest star so far identified in the constellation of Orion is Betelgeuse.Ĭharles Messier catalogued three deep-space object(s) within Orion's boundary. There is a dedicated page for exoplanets in Orion. There are nineteen Extrasolar Planets in this constellation, detailed on this site. The twelve Zodiac constellations are the constellations that lie on the Ecliptic. The Earth is tilted at an angle of 23.44°, which is why the two differ and why we have seasons. The Ecliptic is the path that the Earth takes around the Sun. The Celestial Equator is the projection of the Terrestrial Equator into space. Orion lies south of the Ecliptic, which is different to the Celestial Equator. The celestial hemispheres are a projection of the terrestrial hemisphere into the sky. Any with a higher magnitude can only be seen with a telescope or binoculars. Naked eye stars are stars which have an apparent magnitude of 6.5 or lower. Orion has 225 stars can be seen with the naked eye on a clear night sky. The Hipparcos satellite scanned and detailed one thousand nine hundred and fifty-two stars. Orion has 17 stars that make up the constellation. Orion is the 26th largest constellation in terms of size in the night sky. degrees of the night sky, equating to 1.44% of the night sky.
