I went out to my backyard to take out my dog to do its business. i look up to the sky because i like to look at the stars. i wanted to see if i could see a shooting star. and that's when i see a star moving. at first i think, nice a shooting star but it just kept going and very slowly, like really slow. i begin to think it's a plane but the light looks to small to be a plane and it's not blinking as plane lights would. as i continue to look, i realise there is a grey circle around the light. the light is right in the center of the grey circle outline. in the spaces inside the circle and the light it almost looks transparent. it look just as the black sky. so pretty much all that is visible is the grey circle outline and the white small light that very strongly resembles a star. as soon as i realise that what i'm starting it is not a plane, i slight freeze. not in fear, just in pure awe that i'm standing here staring at a ufo. i just kept looking at it as it continuedoes to move slowly in a straight path. i was hoping for it to stop or turn to truly confirm my suspicions of it being a ufo, but it only continued to move straightforward. i lost sight of it as the house next to me blocked my view of where it went. i didn't think to take a picture because i know my phone can't capture the stars so how could it capture this that is as small and dim as a star. i was upset once i couldn't see it. i went inside and called my mom outside. i told her about it and i tried to look for it once again but i couldn't find it and neither my mom.
