What did johannes kepler discover about the motion of the planets?

Kepler's three laws of planetary motion are the following:

Johannes Kepler discovered three laws of motion of the planets:

1. Law of Orbits: planets move in elliptical orbits.

2. Law of Area: a line that connects the planets to the sun "sweeps out" equal area in equal time.

3. Law of Periods: "The square of the period of any planet is proportional to the cube of the semi major axis of its orbit."

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
