It is not a homework, it is my question, and I hope it is explained.
Sometimes at night I look ATTENTIONALLY at the starry sky , notice and see that there is an object which is as small as a star is moving. It is very very far and has the light as the light of a star, and I FEEL that the DISTANCE from my eyes to it is equal the distance from my eyes to stars. This object IS MOVING AND ALWAYS AVOID TO HIT STARS. One time, I thought it was a satellite, but a satellite is not BIG enough to BE seen at such a distance. There were also many times I saw two objects and one time I saw three objects, they are flying in parallel. What are these objects?
The objects you are observing in the night sky that appear to be moving and avoiding the stars are most likely satellites. Satellites are man-made objects that orbit around the Earth and are used for various purposes like communication, weather monitoring, or scientific research.
To confirm whether the objects you are seeing are indeed satellites, you can follow these steps:
1. Observe their motion: Satellites typically move in a straight line across the sky and maintain a constant speed. They do not change direction suddenly or exhibit erratic movements like aircraft or shooting stars.
2. Check the timing: Satellites can be visible during specific periods of the night when sunlight reflects off their surfaces and makes them visible from the ground. You can use online satellite tracking websites or apps to determine if any known satellites were passing overhead during your observation time.
3. Look for patterns: Satellites can sometimes appear in groups or formations if they are part of a satellite network or a specific mission. If you consistently see two or more objects flying in parallel, there is a higher likelihood that they are satellites.
4. Rule out other possibilities: Be sure to eliminate other potential sources such as aircraft, drones, or meteors. Aircraft often display blinking lights and have distinguishable flight patterns, while meteors typically move very quickly and might leave a visible trail.
By following these steps and considering the characteristics of the objects you are observing, you can determine if they are indeed satellites.
