UFO Sighting in Addison, Vermont on July 11th 2015 – 2 following each other separated by a few stars distance between them

me & my 2 children plus the campers beside us...all camping at DAR state park by the campfire around 10pm my daughter noticed a white round object going overhead at star level, it was a very clear night, & these were higher than the jet that passed by 15 minutes before it came from the south & was going north, if a star looks like a speck of dust this was pill size on the first pass,I thought maybe it was the space station. on its second pass maybe 15 minutes later it was considerably smaller but close to the same path about 20 minutes prior, odd I had a feeling we were going to see one prior to this then we spotted together another one some time after that moved near a star, it stopped, went some more from the south to the north & then shot off to the NE very fast like I know of nothing that can stop its flight all was quiet until 11:45 pm when she spotted 2 separated by a couple of stars distance between them both going north, they went about half way across the horizon when all of a sudden they disappeared, the 3 of us all seen this the campers beside us i think saw them too, but was hesitant to acknowledge though they too were looking into the sky with us at this point my children & I became , nervous, scared & retreated to bed, its odd that several of us all seen the same objects they were all round white luminescence, its no plane or jet that I have ever seen
