info_outlineFrom July 5, 2023.
A new asteroid has been discovered with an orbit that crosses our own planet’s orbit. In general, this object and Earth are very good and not trying to occupy the same space at the same time, and we’ve managed to coexist for a fair amount of time. We are going to have a close approach, however, in 2046, and for the first time in a long time, the potentially dangerous asteroids list actually gave us something to worry about. (This episode originally aired on television March 18, 2023.)
