What is the biggest difference between the Geocentric Model and the Heliocentric Model?
the shape of the planets' orbits
the movement of the moon
the center of the solar system
the movement of the sun
He was able to combine what he saw of the stars' movements with mathematics to predict the movement of the planets. In order to make his predictions true, he worked out that the planets must move in epicycles, smaller circles, and the Earth itself moved along an equant. None of this was true, but it made the math work for his predictions.

Aristotle
Galileo
Ptolemy
How did Brahe contribute to the formulation of Kepler’s laws of planetary motion?
Kepler’s laws of planetary motion are just modified versions of Brahe’s conclusions about the motion of the heavenly bodies.
Brahe provided the mathematical insights to help Kepler analyze the data he collected about the motion of the heavenly bodies.
It was Brahe’s extensive and accurate observations that serve as raw data for the formulation of Kepler’s laws of planetary motion.
Brahe independently developed the same laws of planetary motion as that of Kepler’s and Brahe’s ideas helped Kepler improve his version of the laws of planetary motion.

Which statement JUSTIFIES the expansion of the universe?
The relationship of the distance of distant galaxies from earth and their recessional velocity showed that the further the galaxy the faster they move away from earth, meaning the universe is expanding.
The relationship of the Doppler shift of the distant galaxies and their recessional velocity showed that the galaxies with greater redshift in their spectral lines the faster they move away from earth, meaning the universe is expanding.
The relationship of the distance of distant galaxies from earth and their recessional velocity showed that the further the galaxy the slower they move away from earth, meaning the universe is expanding.
The relationship of the Doppler shift of the distant galaxies and their recessional velocity showed that the galaxies with greater redshift in their spectral lines the slower they move away from earth, meaning the universe is expanding.

Why CAN’T small planets like earth be detected by either Doppler shift or transit method?
Small planets are undetectable.
Small planets cause too much change in the parent star’s path of orbit.
Small planets decrease the star’s brightness significantly, hence undetected.
Small planets do not cause significant change in the parent star’s orbit and brightness.
