Podcaster: Steve Nerlich
Title: Dear CA #056: Objects, Near Earth Objects
Organization: Cheap Astronomy
Links: http://cheapastro.com
Description:
– How many near-Earth objects do we need to worry about?
The definition of a near-Earth object is any solar system body whose closest approach to the Sun is 1.3 astronomical units.
– Does The Goblin change our thinking about the hypothetical Planet 9?
Well, maybe – but it doesn’t change our thinking much. On the first of October 2018, the discovery of a new solar system body was announced – called 2015 TG387. The TG is just a catalogue reference, but since it was discovered just after Halloween someone decided that should stand for The Goblin.
