(CNN) There is a possibility that two inactive satellites currently in low Earth orbit will collide on Wednesday above the US, according to space debris tracking service LeoLabs. If the two satellites crash into each other, the collision will result in thousands of pieces of small space debris which will pose a massive risk to other satellites in space. LeoLabs tweeted Monday that astronomers are monitoring the close approach of two decades-old satellites which will come within 13 to 87 meters of each other at 6:39 p.m. EST. While 1 in 1,000 sounds very unlikely, that probability poses an extremely high risk in the space industry. Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, told CNN that the likelihood of the satellites colliding is "extremely alarming."
