Does Alpha Centauri A, or B, wobble on its axis. If it did that would
mean there would be a possibility of planets around it, wouldn't it?
A triple star system in the constellation Centaurus:
A and B form a visual binary that is seen as the third
brightest star at magnitude -0.27. The third component,
Proxima Centauri, is the closest known star to our sun
at 4.3 light years. as of now, there is no observation
of a star wobbling on its axis, and if there were that
could indicate planets or a dark companion star. when
Hubble is fixed later this year, it might be able to
observe star wobble.
