Kepler's Laws| LATEST Astronomical Unit (AU) - the average distance between the earth and the sun Eccentricity - the degree by which the shape of an orbit differs from a circle Ellipse - An elongated circle, or oval shape, the shape of the planet's orbit. Gravity - A force of attraction between objects. Kepler's 1st Law - The orbit of each planet around the Sun is an ellipse with the Sun at one focus. Kepler's 2nd Law - A line connecting the sun and a planet sweeps through equa...

Geostationary Satellites (Goes) Stationary with respect to a fixed point on Earth's surface (revolves at the same rate as Earth) -Far from earth (36,000 km) = coarse spatial resolution, but good temporal sampling. Visible satellite appears black where the sun is not hitting earth. See lots of black Infrared satellite shows a picture of the whole earth- also shows white around the whole earth. reads the surrounding temp of earth, so the universe is cold, shoing white. ...

Hubbles Law - there are many galaxies - the univ...

. Indicate the process that is responsible for the following aspects of the Earth: a. Day and Night (24 hours): We get day and night because the Earth spins (or rotates) on an imaginary line called its axis and different parts of the planet are facing towards the Sun or away from it. It takes 24 hours for the world to turn all the way around, and we call this a day b. A Year (365 days): A year is the amount of time it takes a planet to orbit its star one time. c. Change in the direction of ...
