what star is the farthest away from earth?what planet is the farthest away from earth in all galaxies?

Answer 1

We don't know, but the quasars we can see are more than 10 billion light-years from us. We have discovered planets around some of the stars in our small corner of the galaxy, but we don't have the observational precision to discover planets in other galaxies. Presumably stars in other galaxies have planets also, so the farthest planets would be in the farthest galaxies. But we won't be able to identify any particular planet without going there to see, and that's not likely within the lifetime of humanity.

Answer 2

All the stars you see in the sky at night come from our own galaxy, the Milky Way. Stars in all other galaxies are not usually observable as distinct stars. Not that stars don't exist in other galaxies but I cannot give you the name of a known star. And if I do, this is going to be a supernova, which is already a dead star. But the most distant galaxy known so far is 13 billion years away from us (we expect this galaxy to contain mostly massive stars). So, there's your answer for the first part.

Regarding planets, the most distant planet known so far is TrES-1 b, which is in our Milky Way at a distance of 150pc (489 light years) away from us.

Answer 3

At this time no one can answer that question, or the second one, either, and be absolutely correct.

What we can tell you is that the Earth is at the center of an observable sphere that has a radius of 40 Billion Light Years in all directions. Distant galaxies have been observed at about that distance from us. Now, "observable sphere" means that we can "see" out to a distance of about 40 Billion Light Years with the very best optical and radio equipment available to us. Beyond that our equipment fails to produce any meaningful or useful information. So our equipment limits the distance we can see.

Now, planets orbit around stars. So if there are galaxies full of stars out there, then in all probability there are planets orbiting the stars in those galaxies. However, just like looking into an automobile's headlights at night, the brilliance of the stars blinds you and prevents you from seeing those other planets orbiting around the stars. (Planets themselves do not shine, they only show reflected light)

Recently astronomers have cataloged more than 200 extraterrestrial planets orbiting around distant stars. They did this by noting the changes in emitted light from the distant star as a planet orbited around it and interupted the light rays coming from it. This is a rather hard way to collect information, but it worked on some of the largest planets orbiting distant stars. It will not work for the smaller planets though.

Distant galaxies contain billions of stars within each galaxy.
There are tens of thousands of other galaxies besides the Milky Way Galaxy. So, gosh knows how many total planets there really are out there. Each star could have from 0 to 10 (or more) planets with their associated moons orbiting around them. That is a vast number of objects out there in deep space. I cannot begin to count that high. So, point of this lesson is... don't let anyone tell you the distance to the fartherest star out there. We just don't know how far that thing is yet, but it is at least 40 Billion Light Years away, and in the near future maybe we will be able to see out to 60 Billion Light Years distance because of some new technology or amazing new development. It only takes the pursuit of one new idea.

Answer 4

Yeah, we don't know yet. Plus, it's going to be constantly changing. Galaxies rotate at a rather high speed, so just because one star is the farthest away today doesn't necessarily mean it will be tomorrow.

People really need to stop thinking of the universe as a static entity.

Answer 5

you do no longer seam to correctly known how great the universe is and what the out come could be if yet another sunlight replaced into to be marvelous out factor our photograph voltaic gadget. If there replaced right into a sunlight we could say hive circumstances the gap our photograph voltaic gadget covers, here is what might take place over the years, the gravity of the sunlight and the planets in each photograph voltaic gadget might act upon one yet another and over the years the two photograph voltaic structures could be pulled jointly and reason a huge catastrophe. There are different photograph voltaic structures purely around the line from our photograph voltaic gadget, and the gap is somewhat close once you check out the vastness of the universe, there are different planets that possibly ought to contain existence basically a trifling ten mild years away. here is something which you will initiate questioning approximately, there's no initiate and no end to the size on the universe.

Answer 6

If you look at the big picture of the Milky way galaxy, and if we could see the farthest star from us in our galaxy , we would have to look through the galactic bulge, which is so concentrated with stars, and if we could, we would have to say that this group of 100,000,000 stars is the furthest from us and not any one particular star. And the group of stars that is furthest from us is at the end of the Sagittarius arm.

Answer 7

Wow, either people ask questions which any first-grade moron should know the answer...or they ask questions which humans are unlikely to ever know the answer. This one is of the latter.

That said, the farthest we have currently seen a galaxy is about 13 billion light years...so there's a ballpark figure for you. (Until we build a better telescope.)

Answer 8

No one knows yet.. the universe is far too massive, and as it is, we can see many galaxies but can only guess if they might possibly have stars that have planets around them.
Sorry...

Answer 9

Furthest star? Probably the one that blew up in a hypernova, creating GRB 050904, with a redshift of 6.24.

We only know of very nearby planets, orbiting nearby stars, because those are the only ones we are currently capable of detecting.

Answer 10

we cant see or know anything about that, we dont even know how many galaxies are in the universe, much less a specific star
