Jagged edges on spritesheet animation

I am new to 2D animation and I'm trying to learn how to make animated sprites in unity.

When I play this animation, the edges are fuzzy. If I zoom up very close, it seems to get a little better, but never fully corrects itself. The image is over 1000 pixels wide and tall so from what I've read so far it is doing that because of something to do with scaling on the screen.

I realize the gif isn't that great but hopefully you get what im saying. the gif actually shows the fuzziness as worse than it is also
