What is the volume of the Milky Way galaxy?
about 8 trillion cubic light-years
Its about 100,000 to 180,000 light-years across and 1000 light-years thick. According to my buddy and famed astronomer Phil Plait (of Bad Astronomy), the total volume of the Milky Way is about 8 trillion cubic light-years.
How big is the Milky Way in MPC?
10 million light-years
The Local Group is the galaxy group that includes the Milky Way. It has a total diameter of roughly 3 megaparsecs (10 million light-years; 9×1022 metres), and a total mass of the order of 2×1012 solar masses (4×1042 kg).
How many Earths can fit in the volume of the Milky Way?
Plugging in our thickness and radius we get about 6.7 X 10^(51) km^3. Dividing the volume of the Milky Way by the volume of the Earth, you get (6.7 X 10^(51))/(10^12) =~ 6.7 X 10^(39) Earths that can fit in the volume of the Milky Way galaxy.
How thick is the Milky Way galaxy on average?
1000 light years thick
The thickness of the Milky Way’s disk depends on where you are in the galaxy. It’s thicker nearer the centre and gets thinner as you move out towards the edge. But on average it is 1000 light years thick.
What is the volume of universe?
The estimated volume of the observable universe is 4 x 1080 m3. Mass is the product of density and volume; using the critical density gives a mind-boggling mass of 4 x 1054 kilograms of matter of all types in the observable universe.
What is the volume of disc?
The volume of each disk is πr2Δx, where r is the radius of the specific disk and Δx is its height. There are two crucial steps to the problem.
How big is the Milky Way in diameter?
105,700 light years
Milky Way/Diameter
Is the Virgo supercluster bigger than the Milky Way?
The Virgo Supercluster’s volume is very approximately 7000 times that of the Local Group or 100 billion times that of the Milky Way.
What is the density of universe?
The expansion rate we see today indicates that the critical density of the Universe is about 9×10-27 kg m-3. This density, however, is the total density of both matter and energy.
