Crash Course Astronomy #4

Bye scientists! I hope you enjoy this video!
P.S the guy in the video is not me!

PLUTO!

Hi scientists! Today's post will be about our special planet, PLUTO! If you scientists knoe me, you know I am in love with Pluto, and I want him to become a planet again, so I do as much as I can. Okay, are you ready to know more about Pluto? Let's go!

A single day on Pluto is roughly equivalent to 6.4 days on Earth, as it takes Pluto 153 Earth hours to rotate once on its axis. By the time Pluto orbits once around the sun, 248 years have passed on Earth. If Earth was the size of a nickel, Pluto would be the size of a head of a pin. It is two-thirds the diameter of Earth's moon.

Pluto cannot support any forms of known life, but scientists believe there may be an ocean hidden underneath its surface. Pluto is similar to a comet in that its atmosphere expands when approaching the sun and contracts when moving away from it.

Pluto was named by 11-year-old Venetia Burney of Oxford, England in 1930. She named it after the Roman god of the underworld. Her grandfather sent her suggestion to the Lowell Observatory and it was accepted. Pluto's five known moons are also named after mythological figures associated with the underworld: Charon, Nix, Hydra, Cherberos and Styx

Earth's Orbit

 

	Picture Earth as it travels around the Sun—a rather small blue sphere with one moon. Earth is one of
	nine planets circling the Sun. The solar system is made of the Sun and its nine planets along with many moons, asteroids, and comets. The Sun, planets, and moons are all nearly spherical, or ball-shaped.
	The Earth and the other planets each follow a path called an orbit around the Sun. Orbits have elliptical paths. Elliptical describes a shape like a slightly flattened circle. Likewise, the Moon moves in an elliptical orbit around the Earth. Trace the elliptical shape of the orbit shown in the diagram in the margin above. Notice how the planet moves slightly closer to the Sun at certain parts of the orbit.
	One full orbit is called a revolution. Earth’s revolution around the Sun lasts for just a few hours longer than 365 days. This period may sound familiar to you. It is one year. Likewise, the Moon’s revolution around the Earth takes about 28 days. This is about a month. In fact, the wordmonth comes from the word moon.
	Just as gravity keeps you on the Earth, gravity keeps the Earth and other planets in their orbits around the Sun. Gravity also keeps the Moon orbiting around the Earth.
