In short: Kepler-22b is often hailed as Earth 2.0, a potential haven for life. This video explores the staggering physical and temporal barriers that make reaching this distant world a monumental challenge for humanity.

While Kepler-22b is a 'super Earth' orbiting a G-type star similar to our own, its distance creates a massive logistical hurdle. Discovered in 2011, the planet has a mass of 9.1 Earths and a radius 2.1 times that of our home planet.

It orbits its star every 289.9 days at a distance of 0.812 AU, placing it within the habitable zone where liquid water could exist. Despite its similarities, the video highlights the 'massive, silent problem' of travel time that headlines often overlook.
