You know big brothers. They're always taking your stuff, eating your food, and perpetually finding any excuse to pick on you at their disposal.
Enter Jupiter - our big brother.
This giant of a planet has been eating our Snickers bars for the past few billion years, but at the same time, Jupiter's wide girth has prevented some major beat-downs directed toward Earth.
For example, just last week, Jupiter got served a black-eye in comet form - Taking one for the team.
I guess sometimes, brothers do serve a purpose.
P.S. this does not pertain at all to my own brother - who is awesome.
