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.

The method of induction is typically used to prove statements about integers within mathematical proofs, but we can attempt an analogy to argue for the similarity of the night sky over distances like 1,900 miles.

Step 1: Define the Claim

We aim to show that two observers separated by 1,900 miles see essentially the same night sky. This means the arrangement of stars and celestial objects appears nearly identical.

Step 2: Base Case

Consider two observers who are standing very close together—say, just a mile apart. At such a small separation, the difference in their viewing angles of celestial objects is negligible, meaning they see essentially the same night sky.

Consider that you can repeat this step for a third person, compared with the second person, and then compare the night sky for the third person and the first, and so on.

Step 3: Inductive Step

Assume that for a given separation distance d, two observers see nearly the same night sky. We now show that an observer moving an additional small distance \Delta d (e.g., a mile farther) still sees nearly the same sky.

Since the stars are incredibly far away—on the order of light-years—the difference in viewing angle due to moving a mile (or even dozens of miles) is minuscule. The shift in perspective for each star, given the vast distances involved, is negligible. Therefore, if the night sky is essentially the same for an observer at d miles, it will also be the same for an observer at d + \Delta d miles.

By repeating this argument iteratively (inductively increasing the separation distance in small increments), we extend it to any large distance, including 1,900 miles.

Step 4: Conclusion

By induction, the night sky remains nearly identical for observers as we increase their separation gradually, even up to 1,900 miles. This is because the stars are so far away that their apparent positions do not change significantly over such distances on Earth.

J/k, it’s totally different unless you are both on the same rotational plane.

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.

Our planet is spherical. No way N.Pole and S.Pole would have similar star pictures.

No, they change out the sky backdrop every 1,000 miles or so

I got to go to the other side of the world once and was amazed at the night sky.

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.
