![]() Mintaka is located at around 1.200 light-years / 380 parsecs away from the Sun. Since Mintaka’s age is unknown, it is uncertain whether all of its companion stars formed at the same time or at different intervals. At a certain point in time, gas and dust from Orion’s molecular cloud, were pulled together by gravity and resulted in the many stars we now see in Orion, and thus Orion’s Belt. As such, the star's age cannot exceed 12 million years. ![]() Mintaka – Delta Orionis –belongs to the Orion OB1 association in the subgroup OB1b which is part of the Orion Molecular Cloud Complex – a star-forming region with stellar ages ranging up to 12 million years old. Its age is also elusive but it is clearly much younger than our sun, in fact, all the stars in Orion’s Belt are. Mintaka is the most complex stellar system out of the stars forming Orion’s Belt. All the three stars in Orion’s Belt, for example, have many other companion stars around them, thus they form multiple star systems (with the exception of Alnilam). Star formation is pretty active in this region. The constellation of Orion is home to many blue stars, clusters, nebulae, and clouds of dust and gas. The other two stars forming Orion’s Belt are Alnilam and Alnitak. Mintaka is a word of Arabic origin and roughly translates to “belt.” Orion’s Belt itself was collectively known by many names in many cultures throughout the ages. This asterism has been known for thousands of years and was associated with many myths and religious beliefs. Mintaka is the westernmost star of the famous Orion’s Belt asterism. It is 3.300 times brighter, and its average surface temperature is around 18.400 K. The fifth component, HD 36485, is around 9 times more massive than the sun with around 5.7 solar radii.The fourth, Mintaka B, has only 0.77 solar radii, 0.4 the sun’s luminosity and its surface temperatures are around 5.324 K, similar to the sun’s.The average surface temperatures are estimated to be around 28.400 K It has around 10.4 solar radii and it is 63.000 times brighter. The third star, Mintaka Ab is 22.5 times more massive than our sun.It is 16.000 times brighter than our sun and its average surface temperatures are around 25.600 K. Mintaka Aa2 is 8.4 times as massive as the sun and has around 6.5 solar radii.The ages of all the stars of the Mintaka system are currently unknown but they are part of the Orion OB1 Association, which is part of the Orion Molecular Cloud Complex – a star-forming region with stellar ages ranging up to 12 million years old.Its radius is around 16.5 times that of the sun. It has surface average temperatures of around 29.000 K. The primary star, Mintaka Aa1, is 24 times more massive than our sun. ![]()
