WEBThe Schwarzschild radius of an object is proportional to its mass. Accordingly, the Sun has a Schwarzschild radius of approximately 3.0 km (1.9 mi), whereas Earth's is approximately 9 mm (0.35 in) and the Moon's is approximately 0.1 mm (0.0039 in).

WEBMar 20, 2024 · For a mass as small as a human being, the Schwarzschild radius is of the order of 10 -23 cm, much smaller than the nucleus of an atom; for a typical star such as the Sun, it is about 3 km (2 miles). The Schwarzschild radius is named for the German astronomer and physicist Karl Schwarzschild, who investigated the concept in the early 20th century.

WEBJan 18, 2024 · M⋅G = 10 ⋅ 1.989×1030 kg ⋅ 6.67430×10−11 N⋅m2⋅kg−2 ≈ 13.275×1019N⋅m2⋅kg−1. Divide the result by the square of speed of light (c): 13.275×1019N⋅m2⋅kg−1/ (2.99×108 m/s)2 ≈ 1.477×103 m. Multiply this with 2 to get the Schwarzschild radius (rs): rs = 2⋅1.477×103 = 29540 m = 29.54 km. sun

WEBAn imaginary projectile launched from the Sun's surface would require a velocity of 618 km/s to escape the Sun's gravitational field. Now, suppose the Sun's radius is reduced by half, keeping its mass constant. Then its escape velocity would increase to 873 km/s.

WEBFor a light ray that grazes the sun’s surface, the only physically relevant parameters are the sun’s mass m and radius r. Since the deflection is unitless, it can only depend on \(\frac{m}{r}\), the unitless ratio of the sun’s mass to its radius.

WEBThe horizon’s size turns out to depend only on the mass inside it. If the Sun, with its mass of 1 M Sun, were to become a black hole (fortunately, it can’t—this is just a thought experiment), the Schwarzschild radius would be about 3 kilometers; thus, the entire black hole would be about one-third the size of a neutron star of that same ...
