Hi [Player]. I'm always glad when you come for a visit. It's nice to have some company after all this lonely lab-work.” Unlike its bigger brother Canis Major, Canis Minor, the Little Dog, is the smaller of Orion's two hunting dogs and is located between Canis Major and Gemini. Its constellation is only composed of two naked-eye stars resembling a straight line. Procyon is the brighter star of the two and is known as the "Little Dog Star." This white, yellow star can be located by drawing an imaginary line through the two stars marking Orion's shoulders, Betelgeuse and Bellatrix. And just like Sirius, Procyon is a binary star system with a white dwarf star and is a close neighbor at 11.5 lightyears from us. Malkov, O. Yu. (December 2007).

Believed to be about 175 million years old, M35 is about the size of the full Moon and is barely visible with the naked eye at magnitude 5.1 from a dark sky. M35 is easily visible through binoculars and any size telescope from the city. Just southwest of M35 is a smaller neighboring star cluster, NGC 2158. Use a telescope to spot both clusters side by side. Let's see... perhaps the nitrogen fixation level is affected by nematode secretions... Oh! Sorry. I was pondering some data and I didn't notice you there. Do you need anything?”

The proper name "Sirius" comes from the Latin Sīrius, from the Ancient Greek Σείριος ( Seirios, "glowing" or "scorcher"). [107] The Greek word itself may have been imported from elsewhere before the Archaic period, [108] one authority suggesting a link with the Egyptian god Osiris. [109] The name's earliest recorded use dates from the 7thcentury BC in Hesiod's poetic work Works and Days. [108] In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) [110] to catalog and standardize proper names for stars. The WGSN's first bulletin of July2016 [111] included a table of the first two batches of names approved by the WGSN, which included Sirius for the star αCanis MajorisA. It is now so entered in the IAU Catalog of Star Names. [112] Taurus, the Bull, can be seen to the upper right of Orion. This easily recognizable zodiac constellation is famous for its V-shaped horns and appears to be charging at Orion. Taurus is easy to find and can be seen from the city. Its bright reddish-orange star, Aldebaran, forms one of the bull's eyes and helps find the famous Hyades star cluster. Although Aldebaran appears to be part of the cluster, it is not and is further away but lies in the same line of sight. SiriusA, also known as the Dog Star, has a mass of 2.063 M ☉. [12] [13] [88] The radius of this star has been measured by an astronomical interferometer, giving an estimated angular diameter of 5.936±0.016 mas. The projected rotational velocity is a relatively low 16km/s, [16] which does not produce any significant flattening of its disk. [89] This is at marked variance with the similar-sized Vega, which rotates at a much faster 274km/s and bulges prominently around its equator. [90] A weak magnetic field has been detected on the surface of SiriusA. [91] How's the farming business going? It's corn season, isn't it? I can imagine it being pretty peaceful, working outdoors with plants all day.” Sirius has over 50other designations and names attached to it. [71] In Geoffrey Chaucer's essay Treatise on the Astrolabe, it bears the name Alhabor and is depicted by a hound's head. This name is widely used on medieval astrolabes from Western Europe. [20] In Sanskrit it is known as Mrgavyadha "deer hunter", or Lubdhaka "hunter". As Mrgavyadha, the star represents Rudra ( Shiva). [113] [114] The star is referred to as Makarajyoti in Malayalam and has religious significance to the pilgrim center Sabarimala. [115] In Scandinavia, the star has been known as Lokabrenna ("burning done by Loki", or "Loki's torch"). [116] In the astrology of the Middle Ages, Sirius was a Behenian fixed star, [117] associated with beryl and juniper. Its astrological symbol was listed by Heinrich Cornelius Agrippa.

Sirius A". SIMBAD Astronomical Database. Centre de Données astronomiques de Strasbourg . Retrieved 20 October 2007.In a letter dated 10August 1844, the German astronomer Friedrich Wilhelm Bessel deduced from changes in the proper motion of Sirius that it had an unseen companion. [47] On 31 January 1862, American telescope-maker and astronomer Alvan Graham Clark first observed the faint companion, which is now called SiriusB, or affectionately "the Pup". [48] This happened during testing of an 18.5-inch (470mm) aperture great refractor telescope for Dearborn Observatory, which was one of the largest refracting telescope lenses in existence at the time, and the largest telescope in the United States. [49] SiriusB's sighting was confirmed on 8March with smaller telescopes. [50] van Gent, R. H. (January 1987). "The colour of Sirius in the sixth century". Nature. 318 (325): 87–89.

S2CID 119260068.Sirius is mentioned in Surah, An-Najm ("The Star"), of the Qur'an, where it is given the name الشِّعْرَى (transliteration: aš-ši'rā or ash-shira; the leader). [129] The verse is: " وأنَّهُ هُوَ رَبُّ الشِّعْرَى", "That He is the Lord of Sirius (the Mighty Star)." (An-Najm:49) [130] Ibn Kathir said in his commentary "that it is the bright star, named Mirzam Al-Jawza' (Sirius), which a group of Arabs used to worship". [131] The alternate name Aschere, used by Johann Bayer, is derived from this. [19] Sirius midnight culmination at New Year 2022 local solar time [132] McCluskey, S. C. (January 1987).

The possibility that stellar evolution of either SiriusA or SiriusB could be responsible for this discrepancy has been rejected by astronomers on the grounds that the timescale of thousands of years is much too short and that there is no sign of the nebulosity in the system that would be expected had such a change taken place. [63] An interaction with a third star, to date undiscovered, has also been proposed as a possibility for a red appearance. [70] Alternative explanations are either that the description as red is a poetic metaphor for ill fortune, or that the dramatic scintillations of the star when rising left the viewer with the impression that it was red. To the naked eye, it often appears to be flashing with red, white, and blue hues when near the horizon. [63] Observation [ edit ] Sirius ( bottom) and the constellation Orion ( right). The three brightest stars in this image—Sirius, Betelgeuse ( top right) and Procyon ( top left)—form the Winter Triangle. The bright star at top center is Alhena, which forms a cross-shaped asterism with the Winter Triangle.
