Spin (physics) discrete angular momenta despite having no orbital angular momentum. In some ways, spin is like a vector quantity; it has a definite magnitude, and it has a "direction" (but quantization makes this "direction" different from the direction of an ordinary vector). All elementary particles of a given kind have the same magnitude of spin angular momentum, which is indicated by assigning the particle a spin quantum number. The SI unit of spin is the (N·m·s) or (kg·m·s), just as with classical angular momentum. In practice, spin is given as a dimensionless spin quantum number by dividing the spin angular momentum
AS 314 AS 314 AS 314, also known as V452 Scuti, is a white hypergiant star and luminous blue variable candidate located in the constellation of Scutum. It has an apparent magnitude of 9.85 and can be seen with small telescopes. AS 314 was poorly studied until the year 2000, when Miroshnichenko et al. determined a distance for this star of around 10 kiloparsecs (32,600 light years), a luminosity 160,000 times that of Sun (), a radius 200 times the solar radius (), and an initial mass of 20 solar masses (). It's losing each year (in other words, every 50,000 years)
