The stars are located at a distance of 2.52106 0.14106 ly (1.5941011 8.9109 AU), whereas the whole Andromeda Galaxy is located at a distance of around 2.5106 ly (1.61011 AU).

How far is a star on far side of Milky Way galaxy from Earth?
Researchers in South Africa and Japan identified five stars known as Cepheids that are located on the opposite side of the Milky Way’s disk, 72,000 to 99,000 light-years away from Earth and on the opposite side of the galaxy’s disk. All five stars are located behind the galactic center, which is located in the constellation Sagittarius and is approximately 27,000 light-years away.
How does the travel time of light from the far side of the galaxy to Earth compared to the travel time of light from the near side?
The light from more distant objects takes a longer time to reach Earth, as you discovered in Part B of this lesson. This indicates that we can see more distant objects since they were there for a longer period of time. In other words, things that are further away have aged more rapidly since their light left the sun on its route to the Earth.
Is Pluto closer to Earth than the sun?
Pluto is 39.5 astronomical units (AU) away from the sun on average, according to calculations. That is over 40 times farther away from the sun than the Earth is from the sun.
Can we see a galaxy that is 50 billion light-years away?
Is it possible for us to observe a galaxy that is 50 billion light-years away from us? The answer is no, since it would be beyond of the realm of our observable universe’s boundaries.
What’s the farthest star from Earth?
Icarus, whose official name is MACS J1149+2223 Lensed Star 1, is the star that has traveled the furthest distance in the universe. It is only visible because the gravitational pull of a huge galaxy cluster, which is around 5 billion light-years away from Earth, has intensified the light from it.
How fast is Earth moving through space?
Furthermore, our solar system, including the Earth, revolves around the center of our galaxy at a speed of around 220 kilometers per second, or 490,000 miles per hour. When we contemplate progressively enormous size scales, the speeds that are involved become really incredible!
What distance is 1 light-year closest to?
A light-year is the distance traveled by light in a single year. What is the distance between you and me? One light-year may be calculated by multiplying the number of seconds in a year by the amount of miles or kilometers that light travels in a second, and the result is one light-year. It is about 5.9 trillion miles in length (9.5 trillion km).
How long is a day on Pluto?
Pluto’s day is equivalent to 6.4 Earth days.
How big is the moon?
Mountains, valleys, plains, and craters may be found on Pluto’s surface, which is defined by its geology. Pluto’s temperature can drop to as low as -375 to -400 degrees Fahrenheit under extreme conditions (-226 to -240 degrees Celsius).
How far back into the universe are we able to see explain?
In other words, after 13.8 billion years, you’d expect to be able to look back almost 13.8 billion light years, if you deduct only the time it took for stars and galaxies to develop after the Big Bang.
How long would it take a human to travel one light year?
If we were traveling at the speed of light, which is 186,282 miles per second, it would take approximately 37,200 human years to travel one light year if we were in a space shuttle traveling at five miles per second.
