I think the orb will be the orange time gem (the glow inside of it could be orange) because of some specific reasons:

It's revealed that each Guardian is in search of the time gem.

Quill/Star Lord's reason is because his mother died back in the 70's and has been abducted by aliens and wants to go back in time to stop it.

Gamora was sent by the Collector to add it in his collections.

Drax' family was killed and wants to go back in time to prevent that, and could also be in search for vengeance while at it.

Rocket wants to get it to give vengeance to his captors on to prevent being overly experimented on; Groot's there because of Rocket.
