5 orange glowing orbs floating horizontally across the night sky

I am currently a college student and the other observer, my mother, is a newspaper reporter with a college degree. My mom and I went outside to observe the space station, but instead of that, we saw 4 bright orange orbs float horizontally across the sky in a perfect upside-down kite formation. When the first formation was almost out of sight, another orange orb appeared far behind the others, following the same pathing. They were completely silent.
