Similar to a star and going in a straight line.

I was lying outside my house facing the sky when exactly at 7 : 33 PM i saw an Unidentified Flying Object . I was looking at a star and it was passing near that star that's when I noticed that it was moving . At first i thought it was a falling star but i was wrong .It was similar just like a star and was going from East to North. It was not a falling star as they go downwards not in a straight line . Netihter it was an aeroplane  
 because airplanes have glowing lights below them (on the belly and under the wings ). I see aeroplanes daily and know it was not one of them. It was shining just like a star and was moving at a constant speed (faster than that of an aeroplane). I won't say that i am 100 percent sure that it was a UFO but still i never in 21 years have seen something like this flying in the sky . I didn't had my phone in my hand when I saw it otherwise i would definitely have recorded a video of that incident.
Sounds like a satellite
