According to Copernicus, Saturn could be seen in the middle of the night and during the day time, so Saturn must be ___.
outside of Earth's orbit
inside of Earth's orbit.
between Earth and the Sun
bigger than Earth
Kepler's law about "equal areas in equal time" tells us that orbiting objects
move faster when they are closer
have shorter periods when they have shorter average distance
orbit in an ellipse
have greater gravity when they are closer
the path an object takes as it revolves around a star, planet, or moon
revolve
orbit
rotate
space probe
What does heliocentric mean?
Which will have a bigger force of gravity on the Earth
Jupiter because its big
Saturn because it is far
the Moon because its closest
The Mercury because it is moving the fastest
Jupiter is much larger than its moon, Europa. The center of gravity between Jupiter and Europa is
much closer to Jupiter (within Jupiter)
much closer to Europa
at Jupiter's core/center
half way between to two.
Which letter represents the position where the planet will move the slowest?
(a)
What early assumption of the heliocentric theory caused inaccuracies in many of is calculations?
each planet rotates on its axis
planets move in circular orbits
the moon revolves around the earth
the sun is the center of the universe
Compared to closer planets, planets that are farther from the Sun will
have longer periods.
have more eccentric orbits.
move slower
be smaller
