What was Kepler's First Law?
Planets revolve across the sun in elliptical orbits with Sun at one attention of the ellipse
What best describes the orbit of the Earth around the Sun?
An ellipse that is close to being circular
Which of the following does Kepler's Second Law aid?
When a planet is closer to the Sun, its velocity is greater than when it's far farther away
How did Kepler himself at the start nation this 2nd law?
A line joining a planet and the Sun sweeps out same regions in identical intervals of time
What was Kepler's Third Law?
The square of the time period for an orbit of a planet is proportional to cube of its common
distance from Sun (in different phrases P2 is proportional to a3).
Saturn is about 10 times as a long way from the Sun as Earth is (a = 10 AU, kind of). About how
regularly does Earth orbit the Sun inside the time it takes Saturn to orbit simply as soon as?
About 30
Besides, the discovery that moons orbit Jupiter, what different discovery made by way of Galileo
Galilei, with an early telescope, proved that the Earth is not on the center of the Universe?
The levels of Venus
We noticed that Kepler's third law states that P^2/a^three = regular. What does P represent on
this equation?
