POST CARD
Dear John,
Dear John,
I just got back from my journey beyond our Solar system. My journey began as i croosed the borders of the United States
We left Earth’s
atmosphere and traveled deep into our
Solar System. I saw planets, comets,
asteroids and dwarf planets, all of which
orbit our Sun! Long after I passed
the dwarf plant Pluto, I reached the outer
boundary of our Solar System.
Our Sun’s solar wind blows out into space
carving a protective bubble around
our solar System called the Heliosphere.
It was spectacular to reach the
boundary of our Solar System! I
can’t wait until the IBEX mission
completes its map of the whole boundary.
Sincerely,
Carla
