SOLAR SYSTEM

Detailed explanation-1: -Knowing then that the orbits of the planets are elliptical, johannes Kepler formulated three laws of planetary motion, which accurately described the motion of comets as well. Kepler’s First Law: each planet’s orbit about the Sun is an ellipse. The Sun’s center is always located at one focus of the orbital ellipse.

Detailed explanation-2: -They were derived by the German astronomer Johannes Kepler, whose analysis of the observations of the 16th-century Danish astronomer Tycho Brahe enabled him to announce his first two laws in the year 1609 and a third law nearly a decade later, in 1618.

Detailed explanation-3: -The elliptical orbits of planets were indicated by calculations of the orbit of Mars. From this, Kepler inferred that other bodies in the Solar System, including those farther away from the Sun, also have elliptical orbits.

Detailed explanation-4: -Galileo was born in Pisa, Italy in 1564 and he died in Florence at his house while house-arrest in 1642. Kepler was born in 1571 in a community near Stuttgart, Germany and died in 1630 during a voyage in Regensburg.
