No, Johannes Kepler is best known for describing the laws that dictate how orbits work. The Kepler planets were discovered by the Kepler telescope, a spacecraft named in his honor.

Kepler did not discover ellipses. In 1605 he discovered that the orbits of the planets were ellipses rather than perfect circles.
Johannes Kepler did not discover any planets, but he developed the laws of planetary motion which described the movement of planets around the Sun in elliptical orbits. These laws were crucial in advancing our understanding of the motion of celestial bodies.
Johannes Kepler discovered that planets orbit in elliptical paths around the sun in the early 17th century, specifically around the year 1605. This was a key contribution to his laws of planetary motion, known as Kepler's laws.

Neither Johannes Kepler nor the Kepler Space Telescope discovered Pluto. Pluto was discovered by Clyde Tombaugh in 1930, long after Johannes Kepler died and long before the Kepler telescope was created. The Kepler telescope was built to discover planets in other solar systems, not our own.

Johannes Kepler replaced circles with ellipses in the heliocentric model of the universe.

Johannes Kepler discovered that planets have elliptical orbits in the early 17th century. Kepler's work was based on observations made by Tycho Brahe and his own mathematical calculations. His laws of planetary motion laid the foundation for modern understanding of celestial mechanics.
Johannes Kepler discovered that planets orbit the Sun in ellipses with varying eccentricities in the early 17th century. This became known as Kepler's first law of planetary motion and revolutionized our understanding of planetary orbits.
