Looks of it. Also you can drag "planets" around.
Yesterday I've made an example for making instance orbit around other instance.
In contrast to other similar examples, here speed defined in a normal way (not angular), instance will detect distance to 'target' object automatically, and speed vector is stored in hspeed/vspeed, allowing to detect direction and impact speed easily.
Also code is well-commented, since several parts indeed require some knowledge to understand.
