What is the nearest neighbor of solar system?
Our nearest planetary neighbor to Earth would be Venus, (which is closer than Mars orbiting further away from the Sun). Venus is sometimes referred to as our sister planet, being the most similar in size to Earth. The nearest stellar neighbor to our solar system is Proxima Centauri, a red dwarf not visible to the naked eye, a little over 4 light years away. Close to it, the nearest visible stellar neighbor to us is the binary star Alpha Centauri. The nearest galaxy to us is likely the Canis Major overdensity about 25,000 light years from us, although its status is somewhat disputed. An even closer, unusualy globular cluster Omega Centauri at only 15,000 light years distance might be a dwarf galaxy.
How many light years are we from the black hole?
The supermassive black hole in the center of our Milky Way is at a distance of about 28,000 light-years. The nearest known stellar black hole is at a distance of about 3000 light-years.
Stellar distance are usually expressed in what units?
A light year
How far away is the sun's closest stellar neighbor?
In very round numbers: -- 4.4 light-years -- 278,000 AU -- 2.587 x 1013 miles -- 4.163 x 1013 km
Why isn't it possible for humans to travel to your nearest neighbor Alpha Centauri?
The nearest star is more than 4 light-years away, we do not have the technology to travel that far within a human lifetime.
What units are stellar distances expressed in?
Stellar distances are measured in light-years, which is the average distance between the Earth and the Sun.
What are our nearest galaxies?
Milky Way Galaxy - Our GalaxyOmega Centauri - former galaxy - 0.0183 million light years awayCanis Major Dwarf - 0.025 million light years awayVirgo Stellar Stream - 0.03 million light years awaySagittarius Dwarf Elliptical Galaxy - 0.81 million light years awayLarge Magellanic Cloud - 0.163 million light years awayAndromeda Galaxy - Largest - 2.5 million miles away.
How big is the Milky Way?
The stellar disk of the Milky Way galaxy is approximately 100,000 light years in diameter and about 10,000 light years in thickness.
How big is a stellar nebula?
It is not known how big a stellar nebula, but they are extremely huge. Some stretch over hundreds of light years across and they are the 'birthplace' of stars
Is Andromeda in the milky way?
no. Andromeda is our nearest milky way's neighbor galaxy. so Andromeda is not locate in the milky way. the distance between these 2 galaxies are roughly 2.5 millions light years.
How many lightyears is the nearest star from the earth?
The nearest star to Earth is the sun, at a distance of 0.000016 light years from Earth. The next nearest star, Proxima Centauri, is about 4.2 light years away.
What is the relationship between the milky way galaxy and Andromeda?
They are two separate, independent, rather large, neighboring galaxies, situated about2.24 million light years apart. Each is the other's nearest neighbor galaxy.
