Planet gravity help

How do you make it so that you have gravity around a planet like SUPER MARIO GALAXY but 2D??? I have tried a lot of things but none have worked. Please help!

Have you tried making objects affected by gravity, when in in range of a planet, set angle and speed towards the planet?

What would you say... Platformer or physics?

I would use the behaviors: Bullet and Line Of Sight. If using multiple objects: add these objects to a Family and apply the behaviors to that Family. It's my understanding that using Physics unnecessarily may be wasting the PC's CPU. Keep events as simple as possible. However I'm not a pro and there's probably more fine tuned ways.

Hope this helped you in some way.

What if you want the player to be able to walk on the planet???
