Although Pluto was discovered in 1930, limited information on the distant planet delayed a realistic understanding of its characteristics. Today Pluto remains the only planet that has not been visited by a spacecraft, yet an increasing amount of information is unfolding about this peculiar planet. The uniqueness of Pluto's orbit, rotational relationship with its satellite, spin axis, and light variations all give the planet a certain appeal and should be appreciated by everyone.
Why is Pluto no longer a planet? Mr. Yokley says, "They declared it not a planet because it's just a big frozen rock." That may be true, but Pluto isn't the only one. From Pluto, the Sun is just a tiny point of light. Yes Pluto may be composed of frozen rock and ice, but so is Neptune's moon Triton. Pluto has not yet been visited by a spacecraft so it's clear that assumptions are made about it. So who knows if whats being said about it is true. Hopefully not because then what would we tell the children?
When asked if it mattered that whats been taught during childhood will no longer be taught, Mr. Mariles stated, "I agree to Pluto not being a planet because its mainly made up of gases and it doesn’t fit in the description of a regular planet." Well Earth and the other three inner planets of our solar system (Mercury, Venus and Mars) are made of rock, containing common minerals and metals like magnesium and aluminum. So is Pluto. The other planets are not solid. Jupiter, for instance, is made up mostly of trapped helium, hydrogen, and water. So how is Pluto any different from the other planets.
What makes Pluto so different from the rest of the planets? "I don’t know, they're uniqueness," Ms. Zamora says after being questioned about what makes a planet a planet. She's right of course. Pluto itself is unique for its position and physical characteristics. The inner planets (Mercury, Venus, Earth and Mars) are known as terrestrial planets for their smaller size, solid surface, and...
