 According to a team of the Initiative for Interstellar Studies, a two-ton spacecraft could theoretically have been sent in July 2018 to intercept 2I/Borisov using a Falcon Heavy-class launcher, but only if the object had been discovered much earlier than it was.Launches after the actual discovery date would require a significantly larger launcher such as the Space Launch System (SLS) and Oberth manoeuvres near Jupiter and near the Sun.By September 2019, even an SLS-class launcher would only be able to deliver a payload (such as a CubeSat) into a trajectory that could intercept 2I/Borisov in 2045 at a relative speed of .
