Earth has a mini-moon that has been orbiting our planet since 2017. Astronomers in Arizona first observed the object earlier this month, giving it the provisional name 2020 CD3. Also, a court in the U.K. has ruled that plans for a third runway at London's Heathrow airport are illegal because they don't address the impact of climate change. The ruling could influence decisions on infrastructure projects around the world. That and more, in hour one of Here & Now's Feb. 28, 2020, full broadcast.
