Camera doesnt scale GameObjects when approaching and smudges them

Hi guys,

I probably didn't named this question right, because I don't know how to properly call this bug; that's also why I wasn't able to find any help in forum.

I'm making a model of the Solar system, have a player who can move around with camera attached to him..but the camera is behaving weirdly, for instance, when approaching other planets, they just pop up suddenly, you can't see them getting from smallest to bigger, the same with going away, they just suddenly disappear when the player moves away enough. Or, when I turn on another side, the planet just "smudges" with the camera (I really don't know how to call it) - in the direction of the camera - as you can see little bit on the screenshot.

I also captured Camera settings although I'm not much sure if it's the cameras mistake. I will be really glad for any help :)
