The Milky Way Galaxy is 100000 light years across. The Sun is located about 30000 light years from the galactic center and revolves around it with a period of 2e8 years. All the stars inside the sun's orbital radius is to be concentrated at the galactic center, as if they were combined into one gigantic star.
What is the mass of the galactic center? knowing 1 light year=9.46e15m and the mass of sun is 1.99e30kg. How many of our suns is this equivalent to?
To understand this scenario, let's break it down step by step:
1. The Milky Way Galaxy's size: The Milky Way is estimated to be approximately 100,000 light-years across. This measurement represents the distance from one end of the galaxy to the other.
2. The Sun's location: The Sun is situated about 30,000 light-years away from the galactic center. The galactic center is considered the central point of the Milky Way, around which stars and other celestial objects orbit.
3. The Sun's orbital period: The Sun takes approximately 200 million years to complete one full revolution around the Milky Way's galactic center. This is known as its orbital period.
4. Concentrating stars within the Sun's orbital radius: In this scenario, all the stars within the Sun's orbital radius are imagined to be combined into one enormous star located at the galactic center. This is a hypothetical situation where the mass of all these stars is concentrated at one point.
By combining these pieces of information, we can have a clearer picture of the scenario you described.
