Draw a picture of beta star. This +4-magnitude star has no features. It is the first time to find a protoplanetary disk made of primitive matter around it-it may be described as a planetary system in the near future, but it is impossible for professional astronomical telescopes to see this disk.

Kapteyn is a red dwarf star with a magnitude of +8.8, which is 2.78 light years away from the sun/kloc-0. It is second only to Barnard in Ophiuchus at a speed of 8.7 arc seconds per year.
