I wanna know that

On your Learner Homepage (the page you see when you first log into Khan Academy), you should see a badge summary on the top-right, just below the "Edit Profile" button.  Click that summary.

A new page will open, listing the badges you have earned and, below them, the available badges. Each listing includes the badge name and the requirement you must meet to earn that badge.

By default, you will see the Meteorite Badges.  Across the top, there are icons for "Challenge Patches", "Black Hole Badges," "Sun Badges," "Moon Badges," and "Meteorite Badges."  Click the icon for the set of badges that you wish to see.

Try to do different courses  hope this helps

It is sow fun

You may notice that others have badges that you don't see on your end. That is because they are retired and cannot be earned any longer.

Can anyone rate my programming projects? Plis 

There are currently over 9,000 projects in the evaluation queue.  Please be patient.

In my opinion awesome listener is the best moon badge and to get it all you have to do is watch 1 hour of a single topic which could be accomplished easily in the physics, math or chemistry section.

Moon Badges:

You can achieve mastery in different skills to earn moon badges, you can also solve problems correctly and quickly to earn moon badges, and you can earn moon badges for having a certain amount of energy points.

Earth Badges:

Earth badges are hard to earn, but you can earn one by achieving mastery in 50 different skills. All of the other Earth badges are related to community posts that earn a ton of votes. There's also the Earth badges you can get by staying a Khan Academy for certain number of years, and Earth badges for donating.

Sun Badges:

Sun badges to me are by far the hardest to get, as they require you to achieve mastery in different skills, and (I think) earn a ton of energy points.

Blackhole Badges:

Blackhole Badges are unknown, but here are what the main three are and how to get them:

Tesla: Earn a grand total of 10,000,000 energy points

Atlas: Users have to achieve mastery in 1,500 different skills (idk if anyone achieved this yet, wiki says the number goes up when someone does get it).

Artemis: User has to achieve and master an unknown amount of skills (apparently this badge is unobtainable).

Secret Blackhole Badges:

Is Sal: You literally need to be Sal Khan to earn this badge.

Galileo: User has to be a content creator for Khan Academy and has to record 3,000 videos on Khan Academy.

Challenge Patches:

You can get these patches by completing different challenges like:

Doing an hour of code on different coding challenges

Completing all of a coding unit (ex. Complete all of Html coding unit).

Finally Other Badges:

Upon looking at other user profiles, you can see how some of them might've won contests and have gotten badges for them.

I hope this helped!
