The planetoid is being attracted toward another massive object.

The planetoid is beginning to change its type of orbit.
The planetoid is beginning to change its type of orbit.

The planetoid is slowing due to friction.

Answer 1

The most reasonable conclusion in this scenario is:

The planetoid is being attracted toward another massive object.

This conclusion aligns with the principles of gravity, as gravitational interactions can influence the motion of celestial bodies in orbit. The unexpected slowing down might suggest an influence from another mass nearby, which could alter the planetoid's trajectory and speed.
