i was thinking about that recently, if that is a huge distance, does someone see the same night sky?? the same moon and stars?? because it’s a big distance i think, it would make sense for them to maybe see another set of stars further away from the ones that i see!!
i was talking about this with my long distance husband recently, if at night, he sees the same stars i see!!!
It really depends!
If you’re talking latitudinally, for example, they’re 1900 miles down South, then there would be a noticable difference. If the difference was in longitude, then your view of the night sky would be delayed to them depending on the difference in time zone.
If someone is 1900 miles west of you, they will be in (almost) your exact same physical location after a short time (about two hours). If someone is 1900 miles south of you, they won’t. So it depends on the cardinal directionality.
That being said, 1900 miles isn’t that far relative to the circumference of the earth (~25,000 miles), so someone 1900 miles south of you would see mostly the same sky. You’d each see some stars the other couldn’t see, but only near the horizon. About 85% of the sky would be the same (if you could see perfectly to every part of the horizon).
Depends. Do they live 1900 miles north or south of you? Or east/west from you. Because the moon only changes perspective north and south. Better chance if the equator is between you as well.
If you lived 1900 miles West or East, you would see the same sky, just at different times. In this case, the difference in timezones would approximately be the difference in the sky you see. So if your husband is 3 hours ahead, he’d see the same sky about 3 hours before you.
If you lived 1900 miles north or south of each other, your horizon could be pretty different. But the stars directly overhead would be pretty similar.
If you lived on opposite sides of the equator, you might start to see different angles of the sky such that things directly overhead look flipped upside down. People in the southern hemesphere see the moon as upside down to people in the northern hemesphere.

OP, you and your husband should download the Stellarium app. You can compare stars together when you talk. 🙂
thank you very much
You’re welcome. I really like looking at the night sky, hope the ap helps
yea me too!! the night sky here is very nice because the stars are soo bright and the moon is bright too, that’s the advantage of living in a calm city with not a lot of people!!

You had me on the first 95 %, not gonna lie.
I’m glad I didn’t read 100% of it then
math amazing!!
Did ChatGPT write this?
Given odd things like “/Delta d” that seems likely.
Its called Latex you stupid twit. You reported me as a bot for something you don’t understand? Fuck Off.
Our planet is spherical. No way N.Pole and S.Pole would have similar star pictures.
OP is talking about 1900 miles, which is some 3050 km or 27.5° across Earth. One can see more than 150° of the night sky in open areas so one will see over 80% of the stars the other does.
Yeah it’s 7000+ km from Florida to London, yet they both can see the Sun at the same time. You can’t see every star the same, but much of the sky will overlap.
A good way to think about this is time zones. The sun is in a different spot depending on what time zone you’re in, so will everything else be in the sky. Also, it depends on seasons because the earth tilts on its axis.
Planets, the “stars” that don’t twinkle, are sometimes between us and the sun (Mercury and Venus). Those planets have crazy patterns and are the evening and morning stars. The planets that aren’t between us and the sun act consistently (the rest).
Our moon travels around us and isn’t attached to the sun, but is in the earth’s orbit. That’s why a lunar calendar and a sun calendar are so different.
If you are located at the same latitude, you will see the same stars but at different times (like time zones). But if the separation has a north-south component, you will be able to see different stars from each other, because the stars hidden over the horizon to the north and south won’t rotate into view because the rotation is east-west.
That’s a great clarification. There is some overlap, but you’re right, they may or may not see some stars or constellations. The Southern Cross for instance, can only be seen from certain southern state in the US.
I got to go to the other side of the world once and was amazed at the night sky.
No, they change out the sky backdrop every 1,000 miles or so
