How to get black hole badges on Khan Academy

Dec. 7, 2011

The Black Hole badges on Khan Academy are legendary and unknown, so a lot of people want to know how to get them. There was a time when the code describing how the badges could be gained was online. At the time the Atlas badge was awarded for completing 150 exercises. But at that time there were fewer than 100 exercises on Khan Academy.

What Black Hole badges are there?

In addition to the three unknown badges, there are a couple of unique badges that only Sal has, and only Sal can get:

  • Is Sal - Which you can only get if you are Sal.
  • Galileo - Make 3000 videos (there are now other video makers, but none close to making 300 videos).


Of all the black hole badges, the most attainable is Tesla. This badge is awarded for getting 10 million energy points. Several people have got it now, some using various cheat to generate points. But there are enough videos and exercises that you can get this badge without cheating. This video show when I got the Tesla badge:

The Atlas badge is the most changeable of badges, always moving out of reach (except for the one time Ben Eater, lead exercise developer on Khan Academy got it by mistake). It was once for completing 150 exercises, then 250 and then 500. Now it has changed again, to another unattainable number. I suspect that when Khan Academy feels there are enough exercises to cover all of high school maths (or maybe one topic), then they will settle on a number. But for now it is not possible.

That leaves the latest badge, Artemis. I did look up the code for this badge when I was employed by Khan Academy and had access to their code. All I can say is that, like Atlas, it is currently not possible to get this badge.

Um you employes are making khan academy look SOOOOOOOOOOOOOO bad because you're saying it's impossible to get 2 BADGES.I mean if it's impossible to get a badge and khan academy will not settle on it's difficulty,you should just take it off.So many kids in my class are LYING to me that they have it and YOU are making these kids do this

I think that Is the point

JeBron Lames on May 21, 2018, 3:13 p.m.

LOL People are getting mad over a MATH PROGRAM. The black hole badges (such as Is Sal) that are impossible are just a joke...

Spangeee-bobbbb on May 27, 2018, 9:14 p.m.

Like JeBron Lames said, it's a math program! It's two badges! Y'all Are getting mad over a stupid two badges, (which u shouldn't be focusing on if u litterally can't get them), when you don't even pay attention to the fact that
a(this could be a joke)
b(khan provides free, good quality education for all people around the world)!
Just get over it!
it's a measly 2 badges! jeesh
P.S: Charlotte, how are they making khan look bad? It is 2 badges, and not too many people know about them. Plus, lots of people focus on the education part, and not so much on the badges.
Honestly, this is a pointless argument.

I checked out Sal's account, the first badge in her showcase is the Is Sal badge, so it isn't fake and the third one is the Galileo badge so they are real, just exclusive to her (except if you make 3000 videos for the Galileo badge)

Sal is a he just so you know

AyaANdAsWag on June 22, 2018, 10:44 p.m.

I don't see any Is Sal badge. There are only three being shown.

Safwan on Aug. 31, 2018, 3:45 p.m.

You can see it on Sals profile:

Like LeBron James said and Spange bob, khan academy is a math site for kids to learn. You don’t have to get mad at the fact that 2 badges are impossible to get.There are plenty of other badges

iluvchess on Sept. 18, 2018, 10:10 p.m.

sal's profile says that he has unlimited points and joined in the beginning

Im pretty sure to get artemis badge u might have to get all greek mythology questions and quizzes and tests right 100% and first try. Im not sure but if someone is a pro at khanacademy they can try. I want to help rly bad. i just started on my account so......

Someone try this method. They could get the badge and be the first, i dont want credit. If someone gets the badge ill write another thingy.

WeaselRacer on Sept. 21, 2018, 1:32 p.m.

The point of all the badges are to make people go beyond there limits, and for the ones that are impossible to get, say you where Sal and you worked on this website for 30 years its nice to have a badge that is special and no one else can have. if your still CRAZY about it then go change your name to Sal Khan and work for 30 years!

Talongraybill on Sept. 21, 2018, 9:58 p.m.

Can you please give me a black hole badge.I’m not allowed to do anything in-till I get one.

Logan on Sept. 27, 2018, 12:55 p.m.

This was written in 2011 correct? So just because he said something 7 YEARS ago doesnt make it true NOW. They might be obtainable now but as far as im aware, the 3rd one is not obtainable, the 2nd one is.

Biblelover on Oct. 10, 2018, 4:24 p.m.

Even though i'm ten, I know enough to see that there is no reason to make fuss over 5 black hole badges. I may be halfway to getting Tesla, and it really is the only obtainable black hole badge, but i'm not making as much of a fuss over them as some people are.

yeee on Oct. 11, 2018, 10:58 p.m.

Khan Acdemy recently updated it's math section, so has the Artemis badge been changed also?

Ƚɨẝɛ ℛυȵȵɛɼ on Oct. 19, 2018, 12:04 p.m.

Atlas and Artemis are at 1500 skills, and Is Sal gives you 100,000,000 energy points.

Khan Is Helpful

A Random Person on Oct. 28, 2018, 4:07 p.m.

Ugh, I'm not even close to getting the Tesla badge. I only have 303,834 energy points. Why does Khan Academy even put impossible badges in the possible section anyways? It would be sort of frustrating to find that THREE of the Black Hole Badges are impossible to get?

A Random Person on Oct. 28, 2018, 4:10 p.m.

ps how can somebody have infinite energy points makes no sense to me

Skynet on Nov. 6, 2018, 3:50 a.m.

By cheating and hacking, which is much easier than doing an infinite amount of work.

Derp on Nov. 7, 2018, 3:05 a.m.

I just mastered 1012 skills, and was pretty disappointed when i found out i didn't get atlas. Its not rlly that big of a deal, as khan academy is free. I also have 2.2 million energy points, wanting to earn tesla. I do realize that I'm probably never going to get it, xD. Don't argue on such pointless terms.

MrMcFee on Nov. 14, 2018, 6:18 a.m.

I don't see why people are making such a fuss over a badge on a free educational website. And to answer your question A Random Person, Salman Khan is the founder of KhanAcademy, so he can do whatever he wants on it, and he chose to give himself infinite energy points and all the badges. If you guys are trying to find out how to get this badge, you obviously are spending WAY too much time on this website. Of course, Khan Academy is a good website, but if you're spending all of your time on how to get a badge, you should go outside and get some exercise, and make a friend.

I know why atlas is impossible. Sal wants people to make goals. And try hard to get badges. Everyone wants to get the hard badges. So he puts up 3 black hole badges. (There is actually 5.) He doesn’t tell you how to get the black hole badges. That makes people try to get the badge. They do a lot of math and stuff. That makes sal happy. He wants that. Except he knows that the badge is impossible. Back when khan was knew, people thougtht every badge is possible, so they worked hard to get it. But they never did. That’s because it isn’t possible! Sal just wants people to work hard. Don’t let sal fool you.
