What are those star-like, star-size that moves in the night sky????

Question

Are they satellites? I have seen so many of them but never really thought of asking anyone but today.

Answer 1

it can be

1)AN ARTIFICIAL SATELLITE.

Most artificial satellites have curved parts that reflect sunlight back to Earth, from where they appear as small points of light that move across the sky in a few minutes in a straight line. Because most satellites rotate around their axis in a few seconds and aren't perfect spheres, the brightness of satellites often goes up and down in a regular period of a few seconds.

If a satellite enters the shadow of the Earth, then it suddenly no longer reflects sunlight to Earth, so it seems to disappear, as seen from Earth. If a satellite leaves the shadow of the Earth, then it becomes visible again just as suddenly. If the satellite has an orbit around the Earth that is sufficiently high, then it can be seen even many hours after sunset or before sunrise.

2)AN AIRPLANE NAVIGATION LIGHT.

Most airplanes have navigation lights at various extremities that blink at night. If such an airplane passes overhead at great height at night, then it appears as a regularly blinking light (or small clump of lights) that moves in a straight line across the sky. This sounds quite a bit like the description of what an artificial satellite looks like. You can tell a satellite and an airplane apart because (1) airplane navigation lights often have a strong (red) color, and satellites often do not, (2) a satellite looks like just a point of light even through binoculars, while for even a small airplane at 10 km distance details (such as navigation lights on both wings) can easily be seen through binoculars, (3) a satellite never produces sound, but an airplane does. The sound of a high airplane can only be heard from a quiet place.

3)AN AIRPLANE LANDING LIGHT.

When airplanes get ready to land, then they turn on powerful landing lights that shine forward and down a bit. Because airplanes usually have to make some curves to line up correctly for the landing, the landing lights can accidentally shine towards you, and then they look much brighter for a while than when they don't shine directly at you. Of course, airplanes tend to use their landing lights only near an airport where they are about to land (or from where they just took off).

4)A METEOR

A falling star or shooting star or meteor draws a straight trail along the sky of something like 10 degrees long in the blink of an eye. That trail can sometimes continue to glow for a few seconds. Some falling stars give a bright flash near the end. Most falling stars are much fainter than the brightest stars, but some can be much brighter than the brightest stars.

Some people think they have hears sounds that had something to do with a falling star, but such sounds are very rare, if they do in fact exist at all.

From a reasonably dark place you can see (if there are no clouds) a few falling stars every night. At some times of the year there are "meteor showers" during which you can see a few falling stars per hour from a reasonably dark place.

5)A SATELLITE FLASH

Some artificial satellites also have (besides curved parts) large flat shiny parts (for example, solar panels). When such a flat part has just the right orientation relative to both the Sun and the observer, then such a satellite reflects much more sunlight to the observer than the curved parts alone can do. Because the satellites usually rotate around their axis, the required orientation will be rare and last only for a few moments. Such a satellite can therefore show a sudden flash in the sky that lasts only a moment but can get much brighter than any star.

On Earth, there is a similar situation when sunlight is reflected to you from the window of a far-away building (when the Sun is low in the sky). If you wait for a little while, or take a few steps to the side, then the flash disappears again.

The Iridium communication satellites are well-known for producing such flashes.

6)AN AIRPLANE FLASH.

Some parts of an airplane are reasonably flat and can therefore reflect sunlight to the observer, if the airplane has just the right orientation relative to the Sun and to the observer, just like for a satellite flash. In practice, such an airplane flash through reflection only occurs around sunrise or sunset.

Answer 2

Hey i dont think it was satalites, i know exactly what your talking about when you say very faint star like objects very distant away & not a satelite or plane, i just saw again tonight 10 pm west australia jan 8th 2016 & back in aug/sep i saw same thing but more. The way ive always spotted these moving objects is when i focus on a group of fixed stars in the distance and keep looking at them & changing groups of stars until you hit a group that has a moving star passing through it then follow with eyes open wide! Enjoy! ufo i dont know but ufp planet. The two objects i saw aug/sep 2015 both headed in oposite directions from starting point from where i first spotted them (just appeared out of area in space)one headed east then disapeared the other west then made a right angle turn up from where i was standing, without stopping and changed direction again. ?? Pretty strange stuff if you ask me. But thats what i saw. Sorry but it wasnt a satelite or a plane

Answer 3

Maybe a shooting start. Or a high flying airplane. Probably not a satellite - the movement would be too slow for you to realize it. Kind of like at sitting and watching the moon and expecting to see it move.

Answer 4

Most likely satalites. Check the paper, they always tell when to see them and from what part of the sky. They ussualy traverse the sky in about 2-5 minutes, and they are coool...

Answer 5

Either a satellite or an airplane.

Answer 6

Yes

Answer 7

satellites. they move really fast. sometimes you can see flashing light (red) slowly winkle (but faster than that of a star)....but if its got a tail.. you are looking at a comet :)

Answer 8

i think almost all of them are satelites. but i've seen them suddenly change direction and shoot off at high speed... those would NOT be satellites :)

Answer 9

Are you seeing shooting stars ? If you do, make a wish - it might come true.

Answer 10

either planets or satellites.
