Detailed explanation-1: -Astronomers have discovered the largest Tatooine-style planet orbiting two suns in the constellation Cygnus . With a mass and radius nearly identical to that of Jupiter, the planet called Kepler-1647b is 3, 700 light-years away from Earth and approximately 4.4 billion years old, roughly Earth’s age.

Detailed explanation-2: -With a mass 1.06 times that of Jupiter and a diameter 1.52 times that of the solar system’s largest gas giant, Kepler-1647b is substantially larger than any of the previously known circumbinary planets.

Detailed explanation-3: -Mass and orbit It is also the largest circumbinary Kepler planet known. It is 483±206 times more massive than Earth, and 1.52±0.65 times Jupiter’s mass.

Detailed explanation-4: -NASA’s Kepler mission revolutionized our scientific understanding of our place in the cosmos by discovering that: Planets outnumber the stars. Kepler has proven there are more planets than stars in our galaxy-and knowing that revolutionizes our scientific understanding of our place in the cosmos.

Detailed explanation-5: -Most exoplanets are found through indirect methods: measuring the dimming of a star that happens to have a planet pass in front of it, called the transit method, or monitoring the spectrum of a star for the tell-tale signs of a planet pulling on its star and causing its light to subtly Doppler shift.
