How would you describe the relationship between Tycho Brahe and Johannes Kepler?

• Mentor and student

• Business partners

• Father and son

• Rivals

What were some of the contributions of Tycho Brahe to astronomy?

• Accurately observing and documenting the positions of stars and planets

• Inventing the telescope

• Writing influential books on astronomy

What is the name of the observatory built by Tycho Brahe?

• Uraniborg

• Newton Tower

• Copernicus Castle

• Galileoborg

What is the first law of Kepler's laws of planetary motion?

• The first law states that the orbit of a planet is an ellipse with the sun at one of the two foci.

• The first law states that the orbit of a planet is a parabola with the sun at the vertex.

• The first law states that the orbit of a planet is a straight line from the planet to the sun.

• The first law states that the orbit of a planet is a perfect circle with the sun at the center.

What is the second law of Kepler's laws of planetary motion?

• A line segment joining a planet and the sun sweeps out equal areas during equal intervals of time.

• The orbit of a planet is a perfect circle

• The speed of a planet is not constant

• The distance between a planet and the sun changes constantly

What is the third law of Kepler's laws of planetary motion?

• The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.

• The speed of a planet is inversely proportional to its distance from the sun

• The size of a planet's orbit is directly proportional to its distance from the sun

• The orbital period of a planet is directly proportional to its distance from the sun

How did Tycho Brahe's accurate observations of the planets contribute to Kepler's work?

• Brahe's observations were inaccurate and not useful to Kepler

• Brahe's observations had no impact on Kepler's work

• Kepler used Brahe's accurate observations to develop his laws of planetary motion.

• Kepler's work was based on his own observations, not Brahe's

What is the significance of Kepler's work in the field of astronomy?

• He formulated the three laws of planetary motion

• He discovered a new planet in the solar system

• He invented the telescope

• He proved that the Earth is the center of the universe
