You can go further with the basketball Sun analogy and plan a family road trip to get to the beginning of the Oort Cloud (home to billions of comets). This would take the family a distance of about 34 miles from the basketball Sun. You might select a fun destination at this distance so the family can relax and reflect on being at the outer rungs of the Solar System – maybe an amusement park, beach, hiking trail, or Grandma’s house!
Now if you wanted to demonstrate getting to the most distant part of the Oort Cloud, you’d have to go a bit father – about 1,700 miles. You could save that trip for summer holiday. Just don’t forget to remind t he kids that they’re now at the edge of the Solar System as they’re munching on a piece of Grandma’s apple pie.
