If you mean the star Kepler-11, it is at a distance of about 2000 light-years.
If you mean, Johannes Kepler, he was born on December 27, 1571 and he died on November 15, 1630 at the age of 58
I'm pretty sure you're thinking of Johannes Kepler.
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.

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.

Johannes Kepler is credited with forming the mathematics of elliptical orbits.
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.

Johannes Kepler proposed that these planets orbit the sun in ellipses, not circles. That is why we have Kepler's Law of Planetary Motion.

Kepler-22b orbits the star Kepler-22.
