    Solar mass - Wikipedia Solar mass The solar mass ( M☉) is a standard unit of mass in astronomy, equal to approximately 2 × 1030 kg. It is often used to indicate the masses of other stars, as well as stellar clusters, nebulae, galaxies and black holes. It is approximately equal to the mass of the Sun.

  2. Solar mass - Simple English Wikipedia, the free encyclopedia Solar mass Solar mass is a unit of measurement of mass. It is equal to the mass of the Sun, about 332,950 times the mass of the Earth, or 1,048 times the mass of Jupiter. Masses of other stars and groups of stars are listed in terms of solar masses. Its mathematical symbol and value are:

    Solar mass Frae Wikipedia, the free beuk o knawledge Size an mass o very lairge starns: Maist massive example, the blue Pistol Star (150 M☉ ). Ithers are Rho Cassiopeiae (40 M☉ ), Betelgeuse (20 M☉ ), an VY Canis Majoris (17 M☉ ). The Sun (1 M☉) which is nae veesible in this thumbnail is included tae illustrate the scale o example starns.

    I noticed that on mobile browsers (chrome and samsung) the solar symbol becomes a sun emoji. This does not look very good. I tested unicode char 2299 and it shows the correct symbol on PC and mobile. However I have no idea how to modify the special command or macro that does this: 1 M☉ Can someone help please? Thanks

    Ehhm, it occurred to me that if the Solar mass is used as a nonstandard unit, the size of that unit quantity should be separate from the actual Solar mass, like the metre is standardized on an obsolete value of Earth radius. But that is a scientific ideal, which may or may not be implemented in reality (keeping in mind the science-philosophical and...

This article is not a stub, there's just not much more that should be written, more could, but it would be "inflation" for the sake of it.

    I'm just curious where it is written that the symbol for the Sun should be written '☉'. It doesn't appear to be an IAU standard even though it is a common astronomical convention. Is there a style guideline somewhere suggesting it's use? Why not simply MSun? Thanks.—RJH (talk) 22:10, 6 October 2009 (UTC)[] 1. You could do that (subscript Sun or eve...

    Hi, if M☉ is solar masses what is R☉ used in the illustration, maybe this could be added to the Related Units section? Regards Khukri 12:26, 16 February 2010 (UTC)[] 1. I'm guessing that R☉ might be the radius of the sun, but that's just a speculation, someone will need to confirm. (talk) 07:44, 11 March 2010 (UTC)[] 2. Yup, that's Sol...

    Currently, there are two sources cited, 1. the ASA Selected Astronomical Constants pdf file 2. NIST CODATA the first source specifies the solar mass parameter to G M ⊙ = 1.32712442099 ⋅ 10 20 m 3 s − 2 {\\displaystyle GM_{\\odot }=1.32712442099\\cdot 10^{20}m^{3}s^{-2}} and Newton's gravitational constant to G = ( 6.67428 ± 0.00067 ) ⋅ 10 − 11 m 3 k g...

    In the caption to the first diagram: The Sun (1 M☉) which is not visible in this thumbnail is included to illustrate the scale of example stars. There is something wrong with this sentence. If the sun is not visible, then in what sense is it included, and how can it illustrate anything?(Indeed, the sun is not visible, either in the thumbnail or in ...

    It said, “The value of G is difficult to measure and is only known with limited accuracy in SI units”. I cut out “in SI units” as redundant; if you know the value in SI units, you can convert it to any other unit system, easily enuf. Okay?--Solomonfromfinland (talk) 13:59, 25 August 2020 (UTC)[]

    Ten years on the the article still can't make up its mind. Is it about the nominal (IAU-defined unit) mass or the actual mass? The lead says it is a unit and then spends the rest of the article talking about how it is measured and how it varies. The unit is neither measured nor varies; it is defined in terms of an SI base unit, as shown in the info...

    The Solar System [c] is the gravitationally bound system of the Sun and the objects that orbit it. It formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority (99.86%) of the system's mass is in the Sun, with most of the remaining mass contained in the planet Jupiter.

  6. In astronomy, planetary mass is a measure of the mass of a planet -like astronomical object. Within the Solar System, planets are usually measured in the astronomical system of units, where the unit of mass is the solar mass ( M☉ ), the mass of the Sun.
