If you mean "what is kevlar" it's a synthetic fibre that can be woven into cloth or spun into rope. It's very strong and often used in bulletproof vests. If you mean "Kepler" he was an old mathematician/astronomer who figures out a bunch of things about our solar system.
Kepler is a space telescope
No. Kepler discovered the laws using Tycho Brahe's data.
Johannes Kepler was born in Stuttgart, in the Duchy of Wurtemburg (now in Germany) his nationality would therefore have been "Wurtemburger"
The general laws about the planets' orbits were known before Newton - mainly, through the three Laws of Planetary Motion, by Kepler. Newton showed that the movement - as explained in Kepler's Laws - was a result of the laws of motion (especially Newton's Second Law), and of the force of gravitation.
Johannes Kepler, a German astrologer.
Isaac newton discovered the three principles of planetary motion
Johannes Kepler
There are lots of planets in the Kepler series. To answer your question, we need to know to which number Kepler you are asking about.
Johannes Kepler determined that all planets have elliptical orbits.
There is no planet that is simply called "Kepler". The Kepler spacecraft discovered various planets, with names such as "Kepler-4b", "Kepler 11-d", etc.
NASA's space telescope "kepler"
Johannes Kepler proposed that these planets orbit the sun in ellipses, not circles. That is why we have Kepler's Law of Planetary Motion.
I'm pretty sure you're thinking of Johannes Kepler.
Kepler-22b orbits the star Kepler-22.
Heinrich Kepler was the father of famous German astronomer Johannes Kepler
There is no single planet named Kepler; rather Kepler is a prefix added to the designations of planets discovered by the Kepler telescope. Several planets discovered by Kepler, including Kepler-438b, Kepler-442b, Kepler 440b, and Kepler 296f, orbit in the habitable zones of their stars, which means they might have liquid water on their surfaces. Currently we do not have the technology to determine if they actually have liquid water.
The Kepler Space Mission was named after Johannes Kepler. Johannes Kepler was an astronomy. The Kepler Space Mission is a mission to search for a habitable earth like orbiting star.
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.
