Dates are shown in white: day/month.Ī Sun-synchronous orbit ( SSO), also called a heliosynchronous orbit, is a nearly polar orbit around a planet, in which the satellite passes over any given point of the planet's surface at the same local mean solar time. A non-Sun-synchronous orbit (magenta) is also shown for reference. She has a Masters in Education from the City University of New York.Diagram showing the orientation of a Sun-synchronous orbit (green) at four points in the year. Each section requires approximately 5 minutes, each activity varies.ĭolores Peterson was a New York City School Teacher in Community School District 3 for nine years when she produced this lesson plan for Kidseclipse.
Each section leads with a simple question which is answered through the use of words, pictures, animations and activities. This site has been designed to give your class an overview of astronomy and help them understand why a Total Solar Eclipse can happen. © Mark D Phillips Lesson One from Kidseclipse The two planets formed the bottom line of the triangle mimicking the shape of the bridge over the East River in New York City.

Said Lovell, “The vast loneliness is awe-inspiring and it makes you realize just what you have back there on Earth.” They ended the broadcast with the crew taking turns reading from the book of Genesis. That evening, the astronauts-Commander Frank Borman, Command Module Pilot Jim Lovell, and Lunar Module Pilot William Anders-held a live broadcast from lunar orbit, in which they showed pictures of the Earth and moon as seen from their spacecraft. The greatest picture ever taken of the Moon and the Earth: Apollo 8, the first manned mission to the moon, entered lunar orbit on Christmas Eve, Dec. The Moon’s orbit lasts 27 1/2 days, but because the Earth keeps moving, it takes the Moon two extra days, 29 1/2, to come back to the same place in our sky. It takes the Earth one year, or 365 1/4 days, to completely orbit the Sun.Īs the Earth orbits the Sun, the Moon orbits the Earth. The Earth’s path around the Sun is called its orbit. As the Earth rotates, it also moves, or revolves, around the Sun. The Earth, which is the third planet from the Sun, takes 24 hours to rotate. It takes the Sun 25 days to spin, or rotate, completely around. These objects are sometimes called celestial bodies, and they are constantly moving, too.Īt the center of it all is the Sun. Our solar system includes the Sun, nine planets and their Moons, comets and asteroids.
We’re always on the move! Even when you’re standing still, you’re moving! You are moving because the Earth and everything in our solar system is constantly moving.
