Did Shapley used the distribution of globular clusters in the galaxy to determine that the Sun was not at the center of the Milky Way?
Yes, Shapley used the distribution of globular clusters in the galaxy to show that the center of the Milky Way was located much farther away than previously thought. By studying the positions and distances of these clusters, he was able to demonstrate that the Sun was not at the center of the galaxy.
Who was the first astronomer to get a reasonable idea of the size and shape of the galaxy?
The first astronomer to propose a reasonable idea of the size and shape of the galaxy was Harlow Shapley in the early 20th century. He used the variable stars known as Cepheid variables to estimate the size of the Milky Way and its position within it. His work helped establish the notion of the galaxy as a vast, spiral-shaped structure.
Which planet is 31800 mile in diameter?
The planet you are referring to is Jupiter, which has a diameter of approximately 86,881 miles. Mercury has a diameter of about 3,032 miles, Venus has a diameter of about 7,521 miles, Earth has a diameter of about 7,917 miles, and Mars has a diameter of about 4,212 miles.
Diameter in km of Saturn?
120,536 kilometers in diameter.
The diameter of the planet venus is about 650 km smaller than the diameter of earth If earth's diameter is about 13000 km what is the diameter of Venus?
The diameter of Venus is about 95% of the diameter of the Earth. Venus is 12103.6 kilometers in diameter from any reference. (Its slow spin does not produce a bulge.) Earth has an equatorial diameter of about 12756.2 kilometers and a polar diameter of about 12713.6 kilometers.
What was shapleys contribution to astronomy?
In 1918 he used Cepheid variables to estimate the size of the Milky Way. The Shapley Supercluster of galaxies is named after him as well.

When did Alan Shapley die?
Alan Shapley died on 1973-05-13.
When was Alan Shapley born?
Alan Shapley was born on 1903-02-09.
What supercluster do we live in?
The Local group for the clusterThe Virgo Super Clusters for the Supercluster
What is the Milky Way orbiting?
There is no larger rotational group for galaxies. The Milky Way galaxy and the Andromeda Galaxy, as part of the Local Group, are moving generally in one direction, toward an unidentified central mass in the direction of the constellation Centaurus. (This may be a gravitational effect of the Shapley Supercluster.)
