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.
Neutron stars are thought to have high rigidity in the crust, and thus a low Love number: ; [6] [7] isolated, nonrotating black holes in vacuum have vanishing Love numbers for all multipoles =. [ 8 ] [ 9 ] [ 10 ] Measuring the Love numbers of compact objects in binary mergers is a key goal of gravitational-wave astronomy .
Analysis of historical records show that Romano's Star was likely quiescent from 1900 until five outbursts occurred between 1960 and 2010. The brightness is not constant during maximum but shows variations on a timescale of months. The third of the five outbursts was the brightest, peaking at magnitude 16.5. [2]
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 .
HD 15082 (also known as WASP-33) is a star located roughly 397 light years away [2] in the northern constellation of Andromeda. [10] The star is a Delta Scuti variable [11] and a planetary transit variable. A hot Jupiter type extrasolar planet, named WASP-33b or HD 15082b, orbits this star with an orbital period of 1.22 days. It is the first ...

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).
[163] [164] The Milky Way contains an average of at least one planet per star, resulting in 100–400 billion planets, according to a January 2013 study of the five-planet star system Kepler-32 by the Kepler space observatory. [33] A different January 2013 analysis of Kepler data estimated that at least 17 billion Earth-sized exoplanets reside ...
