How do scientists know where our sun is located in the galaxy?
1 Answer
From Hubble Space Telescope data on the motion of stars tending to fall into the Black Hole center of Milky Way.
Explanation:
Hubble Space Telescope data had helped scientists to study the
motion of stars that fall into galaxy center and the (prenatal)
formation of stars from gas spiraling from Milky Way disk. Astute
computation from such data reveals that the Black Hole center is
about 27000 light years from the Earth, in the Sun system. This is
the so-called 2-sd (significant digits) approximation
27 thousand light years
to the distance, and so, the approximation to the Sun's
distance is the same. Now, scientist have started detecting stars
behind the center. In this parlance, far distant stars mean star
clusters.
