2MASS J20500010-1154092 has a close companion detected with AstraLux, |
|
|
but it has not yet been confirmed through common proper motion. |
|
|
However, since the separation is quite small (~0.47") and the |
|
|
brightness and color of the companion is consistent with expectations, |
|
|
the system counts as binary for statistical purposes. |
