- I wonder why pluto is no longer a planet.
- I'll look it up.
- Here we go! In 1930,american astronomer Clyde Tombaugh discovered pluto.
- In 2006 however,changes were made.According to the International Astronomical Union, a celestal body must meet the following criteria to qualify as a planet:
- A planet must be round,a planet must orbit the sun,a planet must have"cleared the neighborhood" of it's orbit.
- This means that as the planet travels, its gravity sweeps and clears the space around it of other objects.
- PIZZA
- pluto does not follow the third rule. It has not yet cleared the neighborhood of it's orbit, but don't feel sad for pluto,
- it has a new title-"Dwarf planet". There are currently five dwarf planets in space, scientists expect more dwarf planets over time.
- cheesecake
- WOW! That was very interesting, it's nice to learn something new every day!
