How does distance between earth and sun compare to distance between earth and nearby stars and galaxies?
Wiki User
∙ 11y ago
We measure distances between celestial objects (such as suns, planets, and galaxies) by a unit of measurement called "AU" which stands for, Astronomical Unit. One AU is the equivalent to 93 million miles, which is roughly the distance from earth to the sun. Let's compare that to the next closest star to us, Alpha Centauri, which is 4.4 light years away, or about 271,930 AUs!
Distances are Immense.

Describe Two ways scientists calculate the age of the universe?
by using the distance from Earth to various galaxies and by calculating the ages of old, nearby stars.
Why are magellanic clouds described as nearby?
The Mellaganic Clouds are two dwarf galaxies, satellite galaxies of our own Milky Way. They are "nearby" only to the extent that they are the closest galaxies to our own. Ferdinand Magellan, the leader of the first European voyage to circumnavigate the Earth, named them because they appeared to be permanent clouds in the southern sky. The Clouds aren't visible from Europe or North America.
Best unit to measure distance to nearby stars?
While lightyears are used in measuring distances between galaxies and suns and the distances to extra solar planets, the measurements inside our solar system (between the planets in our solar system are miles and kilometers. The larger A.U.s (Astronomical Units) or the mean distance from the Earth to the Sun can also be used. An A.U. is equivalent to 149 598 000 kilometers.
Can any galaxies besides our own be seen with the naked eye?
With some luck, good eyesight, and a very dark sky, there are one or two nearby galaxies that can be seen by the naked eye as small splotches.
The distance to nearby stars can be measured by using?
Parallax
What is the distance between stars and glaxies?
Typical distances between nearby stars are in the order of a few light-years; for example, the closest star to Earth (after our Sun) is at a distance of about 4.2 light-years. Typical distances between nearby galaxies are in the order of a hundred-thousand light-years, to several million light-years. For example, the Andromeda Galaxy is at a distance of about 3 million light-years; while that's the closest large galaxy, there are several dwarf galaxies that are closer to us.

Why isn't the look-back time important among nearby galaxies?
Galaxies change very slowly.
What other galaxies do you have in unniverse?
For a start, look up "Local Group" in the Wikipedia. This will show you a list of nearby galaxies.
In which direction are nearby all galaxies moving relative to earth?
Nearly all galaxies are moving away from our galaxie and planet.
Which astronomer argued that the milky way is huge and other galaxies are merely small nearby companions?
Shapley is the astronomer that argued that the milky way is huge and other galaxies are merely small nearby companions.
What is the name of a nearby galaxy?
The Large Magellanic Cloud and the Small Magellanic Cloud are two nearby dwarf galaxies. Two larger galaxies that are still part of our local group are the Andromeda Galaxy (a.k.a. M31), and the Triangulum Galaxy. All of the above-named galaxies can be seen with the naked eye.

How many galaxies are approaching milky way galaxy and how many are moving away related to the cosmological red shift?
Most galaxies are moving away from us. Only a few galaxies, which are nearby, are moving towards us.
How do astonomers measure the distance to nearby stars?
Astronomers use the unit of measure "Light Years" to calculate the distance between pretty much anything in the Universe.
