The Triangulum Galaxy is a spiral galaxy 2.73 million light-years (ly) from Earth in the constellation Triangulum.It is catalogued as Messier 33 or NGC 598.With the D 25 isophotal diameter of 18.74 kiloparsecs (61,100 light-years), the Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Andromeda Galaxy and the Milky Way.
The Love number k is defined as the cubical dilation or the ratio of the additional potential (self-reactive force) produced by the deformation of the deforming potential. It can be represented as k V ( θ , ϕ ) / g {\displaystyle kV(\theta ,\phi )/g} , where k = 0 {\displaystyle k=0} for a rigid body.
A blue band light curve for GR 290, adapted from Polcaro et al. (2016) [2]. Analysis of historical records show that Romano's Star was likely quiescent from 1900 until five outbursts occurred between 1960 and 2010.
The symbol for the first-recognised centaur, 2060 Chiron, was devised by Al H. Morrison soon after it had been discovered by Charles Kowal, and has become standard amongst astrologers. [33] In the late 1990s, German astrologer Robert von Heeren created symbols for other centaurs based on the Chiron model, though only those for 5145 Pholus and ...
33 is the 21st composite number, and 8th distinct semiprime (third of the form where is a higher prime). [1] It is one of two numbers to have an aliquot sum of 15 = 3 × 5 — the other being the square of 4 — and part of the aliquot sequence of 9 = 3 2 in the aliquot tree (33, 15, 9, 4, 3, 2, 1).
The Horsehead Nebula (also known as Barnard 33 or B33) is a small dark nebula in the constellation Orion. [2] The nebula is located just to the south of Alnitak , the easternmost star of Orion's Belt , and is part of the much larger Orion molecular cloud complex .
A star prime is a star number that is prime. The first few star primes (sequence A083577 in the OEIS) are 13, 37, 73, 181, 337, 433, 541, 661, 937. A superstar prime is a star prime whose prime index is also a star number. The first two such numbers are 661 and 1750255921. A reverse superstar prime is a star number whose index is a star prime ...
