221 played this game on Friday… we collected all 12 cards with no problem! So we moved on to something a bit more challenging…

If you want to make this game more challenging for yourself, try filling them in in reverse order, or from the middle out…

Hopefully we’ll be posting more solar system games soon!

Ever wondered how many Earths would add up to one Jupiter? How many Saturns would balance out one Sun? Find out with one of our favorite websites ever, the Planet Mass Comparison. Click one of the pictures below to try it yourself:

One Neptune = 9,501 Plutos!

14 Earths = 1 Uranus.

OK, OK, there’s actually no cosmic scale out in space weighing planets. This is actually measuring mass, which is a bit different than weight. Weight depends on where you’re standing. For example, you’d “weigh” a LOT more if you were on Jupiter or the Sun. (Not that you would survive long enough to get on a scale.) You even weigh a tiny bit less when you’re up in the mountains than you would at sea level. But you are the same size, with the same amount of “matter” inside your body, no matter where you are.

We were debating the other day why this planet might be on its side… what do you think?

Voyager was launched shortly before I was born and has now left the solar system. There is a lot of empty space between stars, so it doesn’t have much to take pictures of right now.

The first Star Trek movie ever made was about what might happen to Voyager if it keeps going on and on and learning more and more… not exactly realistic, but interesting.
