Where does space end and begin?
Outer space does not begin at a definite altitude above the Earth’s surface. The Kármán line, an altitude of 100 km (62 mi) above sea level, is conventionally used as the start of outer space in space treaties and for aerospace records keeping.
Why can you see moon and sun at same time?
The time it takes the Moon to rotate on its axis is the same time it takes to complete one trip (or “orbit”) around the Earth. This is why we always see the same side of the Moon. It also follows a similar path across the sky as the Sun.
Can you look at the sun from space?
Far and away the brightest object in the sky, the sun is easy to find, but it’s so bright that one can’t look directly at it without vision damage. Unlike most satellites, which orbit the Earth, SOHO orbits around the sun itself, like a planet or comet.
How far can the sun be seen in space?
94.5 million miles
What does space station look like from Earth?
The space station looks like a fast-moving plane in the sky, but it will be seen as a steady – not blinking – white pinpoint of light. Typically it will be the brightest object in the night sky (except for the Moon). It is bright enough that it can even be seen from the middle of a city!
How far away are things in space?
Distances in space are really, really big. The Voyager 1 spacecraft is heading out of our Solar System at 62,000 km per hour, but even at that speed, it would take it 77,000 years to reach the nearest star….

What is the farthest we can see in space?
“From previous studies, the galaxy GN-z11 seems to be the farthest detectable galaxy from us, at 13.4 billion light-years, or 134 nonillion kilometers (that’s 134 followed by 30 zeros),” Kashikawa said in a statement. “But measuring and verifying such a distance is not an easy task.”
