Here is a link to a two-minute podcast by Dr Al Grauer from the Spreaker ‘Travelers in the Night‘ channel about how some asteroids can have a comet-like tail, and are also responsible for some meteor showers (the asteroid 3200 Phaethon, which passes very close to the sun, is associated with the Geminid meteor shower; this December 2017 Phaethon will pass ‘just’ six million miles from the Earth).

In order to better understand the links between comets and ‘active asteroids’ we will need more information about their composition from future missions.
