The two stars share a common proper motion, indicating they may be gravitationally bound.

Often that appointment had been kept, high above the Earth where the sky was black and sun and stars shared the heavens together.

Both stars share similar physical characteristics to the Sun, so they are considered solar analogs.

The two stars now share a common envelope, causing their mutual orbit to shrink.

The two stars share a common motion through space and hence most likely form a binary star system.

The stars share the same proper motion so they are probably related.

These stars share a similar motion through space, which may indicate a common origin.
