To earn Atlas, users have to master 5,000 unique skills . Ben Eater has the old version of the badge, which only required 500 unique skills.
Artemis[]

To earn Artemis, users need to master 7,500 unique skills. Because Khan Academy does not yet have 7,500 skills, it is impossible to get this badge.
Galileo[]

To earn Galileo, users have to become a content creator who records 3000 videos on Khan Academy. Because of the low demand for this position, it is impossible for most members to get the badge.
Is Sal[]

To earn Is Sal, users have to be Salman Khan - the founder of Khan Academy. Obviously, it is improbable with current technology for any member (except Salman Khan) to get the badge.
Herculean[]

To earn Herculean, the user has to achieve proficiency in all exercises on Khan Academy. This means you must become proficient in every skill on the site, which amounts to over 7,000 skills by now. However, it appears that this badge is a custom badge, making it impossible to obtain.
