Pluto is a planet

Pluto was a planet but NASA stated that pluto was not a planet but a dwarf planet.

the requirements for becoming a planet

Because Pluto is not large enough to "dominate" its orbit, it is not a planet. (Neptune is about 8000 times more massive than Pluto, so Neptune is a planet and Pluto is a dwarf planet.)

  1. It must be an object which independently orbits the Sun (this means moons can't be considered planets, since they orbit planets)

  2. It must have enough mass that its gravity pulls it into a roughly spheroidal shape

  3. It must be large enough to "dominate" its orbit (i.e. its mass must be much larger than anything else which crosses its orbit)

If the statement is false, then "This statement is false", is a lie, making it "This statement is true." The statement is now true. But if the statement is true, then "This statement is false" is true, making the statement false. But if the statement is false, then "This statement is false", is a lie, making it "This statement is true." The statement is now true. But if the statement is true, then...

The statement that is true about the sun is A: the sun is at the center of the solar system. The sun is indeed at the center of our solar system, around which all planets, including Earth, revolve. It is not at the center of the entire universe, and the idea that the sun revolves around Earth and Earth's moon is a misconception.
