First, to get a little back story on the rather sensitive nature of this week’s astronomy lesson, click here for a link to our Hawaiian homeschool 6 years ago.
Abraham Lincoln once said that just because you call a sheep’s tail a leg that doesn’t mean the sheep has 5 legs. Even though many astronomers say Pluto doesn’t fit their newly revised definition of a planet doesn’t mean it isn’t one. I think Pluto should still be considered the 9th planet because it does fit the requirements of a planet. It orbits the sun, has 5 moons, and is round. Actually it is sometimes the 8th planet, not the 9th, because its orbit brings it closer to the sun than Neptune at some points. Even members of Nasa’s New Horizons team which flew by Pluto in 2015 think it should reclassified. They discovered mountains on Pluto as high as 11,00 feet and other features indicating geological change and complexity. Our classification systems have proven to be faulty in the past and maybe Pluto is an example of that (by Titus, age 15).
