What is the distance modulus for a star that is 1 million parsecs away?
A distance of one million parsecs (approximately 3,262,000 light-years) is commonly denoted by the megaparsec(Mpc).
What is the estimated per second per megaparsec expansion of the universe?
One of the latest estimates is about 67.80Â (plus-minus) 0.77 (km/second)/Mpc. Check the Wikipedia article on "Hubble constant" for more details, and other estimates.
How fast is a galaxy 10 billion light years from earth moving away from us?
The Hubble Constant ... relating distance to speed of expansion ... is currently estimatedas 71 kilometers per second per megaparsec. (Plus or minus 10 percent. The numberhas been hotly debated and actively researched for the past 80 years.)1 parsec = 3.26 light years.10 billion LY = 3,067.5 million parsecs (rounded)Speed of recession = (3,067.5 million parsecs) x (71 kilometers per second per megaparsec) =217,800 kilometers per second (rounded)= 72.5 percent of the speed of light (rounded)
What was Edwin Hubble's equation?
Hubble's equation states that the velocity at which various galaxies are receding from the Earth is proportional to their distance from us.The law is often expressed by the equation v = H0D, with H0 the constant of proportionality (the Hubble constant) between the distance D to a galaxy and its velocity v. The SI unit of H0 is s-1 but it is most frequently quoted in (km/s)/Mpc, thus giving the speed in km/s of a galaxy one Megaparsec away. The reciprocal of H0 is the Hubble time.
How much is the universe expanding each year?
We cannot know for sure, but we're sure that the universe expanded faster than the speed of light. While it is physically impossible for any object to move through space faster than the speed of light (according to Einstein's theory of relativity), it is possible for space itself to expand faster than the speed of light since it is not an object, but the area in which all objects and laws of physics are contained. In fact, space is still expanding faster than the speed of light.
How many kilometers are there in a megaparsec?
A megaparsec is 3.08567758 × 10^19 kilometers.
How many km are in megaparsec?
1 megaparsec = 3.08568*1019 km.
How many cubic angstrom units are there in a cubic megaparsec?
1 parsec = 3.0857x1016 metres = 3.0857x1026 Angstrom units.So, 1 megaparsec = 3.0857*1032 Angstrom units.And then, cubing them,1 cubic megaparsec = 2.938x1097 cubic Angstrom units.
A mega-parsec is equivalent to?

What are the units of length from largest to smallest?
Megaparsec . . . Femtometer
How far is a megaparsec in miles?
According to Wikipedia, a parsec is 30 trillion kilometers. So, a megaparsec is 30 million trillion kilometers. And, since there are about .62 miles in a kilometer, a megaparsec is about 19 million trillion (or quintillion) miles. More precisely, 1 parsec = 3.08568025 x 10^16 meters. So, 1 megaparsec = 10^6 * 3.08568025 x 10^16 meters or 3.08568025 x 10^22 meters. Converting to kilometers, a megaparsec is 3.08568025 x 10^19 kilometers. Converting to miles, a megaparsec is .621371192 * 3.08568025 x 10^19 miles or 1.91735282 x 10^19 miles. This is equivalent to 19.1735282 x 10^18 miles. Since 10^18 is a million trillion (or quintillion), 1 megaparsec = 19.1735282 million trillion miles.
If a constant apparent speed of 1.54 km s by how many megaparsec would the separation between us and a galaxy change over the course of 2.0 billion years?
.00323 Megaparsec
What is the greatest customary unit to measure capacity?
Probably the cubic megaparsec.
71 kilometers per second per megaparsec convert to mph?
71 km/s per megaparsec is an acceleration, not a velocity. Key this into the Google task bar: convert 71 km per second to miles per hour Out pops: In each case this would be the acceleration over a megaparsec (about 3 million light years) Sounds about right for the Hubble Constant.
A kiloparsec is a million parsecs?
A megaparsec is equal to 1 million parsecs
What is the radius of a galactic cluster?
Galactic clusters radii range from 1 to 5 Megaparsecs. A megaparsec is about 3.3 million light years.
5795 kilometers per second per megaparsec convert to mph?
5,795 kilometers per second = 12,963,050 miles per hour (rounded)
