The mass of the galactic center, specifically the supermassive black hole known as Sagittarius A*, is estimated to be about 4.1 million times the mass of the Sun. This mass is concentrated within a region only a few million kilometers across. In addition to Sagittarius A*, the overall mass of the galactic center includes stars, gas, and dark matter, contributing to the complex dynamics of the Milky Way's core.

How far is the galactic center from earth?
The galactic center is approximately 25,000 light-years away from Earth. This region of the Milky Way galaxy contains a supermassive black hole and is a hub of activity with stars, gas, and dust. Astronomers study this area to understand the structure and dynamics of our galaxy.
What determines how much gravity on a planet has?
Its mass. More mass=more gravity Also the distance from the planet's center to its surface, i.e. its radius.
Explain how to calculate the position of the common centre of mass of the Earth-Moon system?
The distance from the center of mass to Earth, times the mass of the Earth, must be equal to the distance of the center of mass to the Moon, times the mass of the Moon. (For more than 2 objects, the calculation is somewhat more complicated - reading about "center of mass" can give you an idea.)The distance from the center of mass to Earth, times the mass of the Earth, must be equal to the distance of the center of mass to the Moon, times the mass of the Moon.

What is the center of the mass of an object?
The center of mass of an object is the point at which its mass can be considered to be concentrated. It is the average position of all the mass in the object. It is the point around which the object will balance in any orientation.
How much do tickets on the Virgin Galactic cost?

How much time does it take for the Sun to Orbit the Galactic Center once?
One galactic rotation at our distance from the galactic center takes about 220 million years.
What is the Galactic Core?
The galactic core is the center (not the very center) of the Milky Way Galaxy.
Which great center contains almost 1 million items?
A galactic centre.A galactic centre.A galactic centre.A galactic centre.
How do you measure the mass of the black hole at the galactic center?
If you observe an object in an elliptical orbit around something, AND you know the mass of the orbiting object AND the size of the orbit, you can calculate the mass of the object at the center (more precisely, at one of the foci) of the orbit. We observe several stars orbiting the super-massive black hole at our galactic center. We can calculate their mass based on the light they give off, and we can measure their orbits over time. From this, we can calculate the mass of that black hole.
It is found at the center of the milky way?
The galactic center.
What is the Galactic Eclipse?
The Galactic Eclipse is a rare celestial event that occurs when the Galactic Center aligns with the Earth and the Sun. This alignment can create a dramatic visual effect resembling an eclipse of the Galactic Center as seen from Earth.
What is the main center of the galaxy?
Galactic centre.
What behavior do galactic rotation curves exhibit to suggest the existence of dark matter in an extended halo?
Galactic rotation curves show that stars orbit the center of galaxies at velocities that do not decrease with distance from the center. This suggests that there is additional unseen mass, or dark matter, distributed throughout the galaxy's extended halo. The presence of dark matter is necessary to provide the gravitational pull required to keep stars at their observed velocities.
Can galaxies orbit each other in space?
Yes, galaxies can orbit each other in space. This phenomenon is known as galactic interaction or galactic cannibalism, where the gravitational forces between two or more galaxies cause them to orbit around a common center of mass.
Does the sun move in an elliptical orbit or does the moon?
Both the Earth and the Moon move in the universe. Earth and Moon actually orbit their common center of mass. Together, the Earth and the Moon orbit the Sun, which itself is moving in the universe.
Where is the galactic center in the constellation of Sagittarius?
The black hole Sag A* is considered to be at the center of our galaxy.
How far is Jupiter from the Galactic center?
The galactic center is somewhere in the neighbourhood of 24 - 26000 light years (around 7600 parsecs)
