Using your reference table, what is the formula to calculate the eccentricity of a planet’s orbit(ellipse)
Distance between foci/Length of major axis
400
A major piece of evidence supporting the Big Bang theory is the observation that wavelengths of light from stars in distant galaxies show a
(1) redshift, appearing to be shorter
(2) redshift, appearing to be longer
(3) blueshift, appearing to be shorter
(4) blueshift, appearing to be longer
(2) redshift, appearing to be longer

How does Gravity depend on the mass of objects? Distance?
The greater the mass of the two objects and the closer the distance between two objects the greater the gravitational force.
