- ◆ Vega is at 25 light-years; Altair is even closer at 16.7 light-years.
- ◆ Altair rotates extremely rapidly (once every 10.4 hours), making it noticeably oblate; Vega also rotates fast but less extremely.
- ◆ Vega is about four times more luminous than Altair.
- ◆ Vega has a prominent debris disk suggesting possible planetary formation; Altair's disk is less prominent.
