This is about the event horizon of a Black Hole
A rough calculation of the event horizon is where light would travel in an orbit around a black hole For a Black hole about 15 times the mass of our sun, this would be about 48 km
I tried to find out the relative mass of one kilogram sitting at this point All that I could find was the relative acceleration.
The effects of gravity on all objects near any star can also be calculated
the formula for calculating acceleration due to gravity:
G is the universal gravitational constant, M is mass, and R is distance. (between objects)
g = G*M/R^2, where g is the acceleration due to gravity, G is the universal gravitational constant, M is mass, and R is distance.
the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. on the Sun, that would be 273.7 meters/sec^2
Mass of Earth 5.972 × 10^24 kg 9.8 m/s2 Radius of Earth 6,371 Km Mass of Sun 1.989 × 10^30 kg 273.7 meters/sec^2 Radius of the Sun 696,000 kilometers
