Question

Select the correct answer from each drop-down menu. Complete the paragraph based on this diagram. A diagram showing a planet in an elliptical orbit around the sun with the sun as one of the foci of the ellipse. Kepler devised three laws to explain the ________ in the universe. According to the first law, a planet revolves around the sun in a path similar to ________ with the sun fixed at one of its focus points.

1) motion of celestial bodies, an ellipse
2) formation of galaxies, a circle
3) expansion of the universe, a straight line
4) evolution of stars, a parabola

Answer 1

Kepler formulated three laws about the motion of celestial bodies; his first law states that planets move in an elliptical orbit with the sun at one focus.

Step-by-step explanation:

Johannes Kepler formulated three laws to explain the motion of celestial bodies in the universe. Kepler's first law, derived from careful analysis of planetary positions, dictates that planets orbit around the sun following paths shaped like an ellipse, with the sun located at one of the foci of that ellipse. This was a significant deviation from the previously held belief that orbits were perfect circles. Understanding Kepler's laws is fundamental for comprehending the principles governing planetary motions and the mechanisms of our solar system.
