Odd Body in Asteroid Belt with 6 Tails

Click For Summary

Discussion Overview

The discussion centers on an unusual body in the asteroid belt that appears to be emitting six comet-like tails. Participants explore the implications of this phenomenon, including its classification as an "active asteroid," potential causes for its behavior, and comparisons to other celestial observations.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants express surprise at the term "Active Asteroid," noting they have not encountered asteroids with tails before.
  • One participant suspects that the body may have been involved in a recent collision, which could explain its unusual features.
  • Another participant humorously suggests that the asteroid looks like it has been used for target practice, indicating a perception of damage or alteration.
  • There are claims that the body may be a confused comet, with ongoing observations to determine its rotational state, potential fragmentation, or the existence of similar bodies.
  • A participant references a scientific paper that hypothesizes the body is shedding mass due to torques from solar radiation, suggesting a possible mechanism for the observed tails.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the cause of the asteroid's behavior, with multiple competing hypotheses presented, including collision involvement and solar radiation effects.

Contextual Notes

Limitations include the speculative nature of the claims regarding the asteroid's behavior and the lack of definitive observational data to support any single hypothesis.

Who May Find This Useful

Astronomy enthusiasts, researchers interested in celestial mechanics, and those studying active asteroids or comets may find this discussion relevant.

the term "Active Asteroid' is a new one for me.
Never heard of or seen as asteroid with a tail before

I suspect it was involved in a 'recent' collision.
 
My friend Harvey says it looks like someone's been using it for target practice!

Other reports have it that it's a confused comet. Certainly, it is an exciting new wonder of nature.

Observers are trying to learn if it is spinning, breaking up, or if there are more of them.

Not long ago, Hubble spotted a peculiar X-shaped object, thought to be the result of a collision, although alternative ideas are not ruled out.

Here is the paper on P/2013 P5 from Astrophysical Journal Letters.
The authors hypothesize the body is showing rotational mass shedding, presumably due to torques imposed from solar radiation.
