Expect some company:

For the second time in just under two years, astronomers have confirmed that we are being buzzed by an interstellar visitor, and some experts estimate that we'll be seeing more of them.

In early September, amateur astronomer Gennady Borisov discovered a comet using a homemade 0.65-metre telescope. Early observations by professional astronomers suggested the orbit of the object took it outside our solar system, though further observations were needed to confirm.

Last week, the International Astronomical Union's (IAU) Minor Planet Center (MPC) was able to calculate a preliminary orbit, which verified that the comet had a hyperbolic orbit — meaning that it is orbiting in a way that prevents it from being captured by the sun's gravity.
