Asteroid 99942 Apophis imaged from my backyard last night on a 100mm telescope. Around 400m wide and 16+ million km away, this was its closest pass until 2029 when it will come as close to Earth as geostationary satellites. (OC)

They should start training the astronauts for well digging now so it’s not so last minute
