Kepler-452
« on: February 23, 2017, 01:04:17 PM »
The Kepler-452 system hosts perhaps the most Earth-like planet found so far.
Kepler-452b.

It is the first potentially rocky and smallest exoplanet found orbiting Sun-like star in the Habitable Zone.
At least confirmed as terrestrial.

G-Type stars are the safest, as they don't emit too much radiation at 1 AU and live a good lifespan.
Like our Sun for example.

Kepler-452b is 1.6x larger than Earth in diameter and 5x Earth's mass.
Making its gravity twice as strong as Earth's, making it hard to walk on, since we'd weigh 2x as much there as on Earth.

But at least that's better than getting hit by too much radiation, and Kepler-452 is a Yellow Dwarf, so no serious radiation coming out like from Red Dwarfs.

Shortly after Proxima b was discovered, it was found that red dwarf radiation would strip away the building blocks of life, including Nitrogen and Oxygen, making red dwarf habitable zones nonexistent despite the planet temperatures.

And better, Kepler-452b is likely to have a day much shorter than it's orbit and closer to that of Earth's rotation.
Whereas Proxima b's day is just as long as its orbit, due to tidal locking.
Making one side hot and one side cold.

So to this day, Kepler-452b remains the most Earth-like exoplanet we've found so far.

Here's the sim for Kepler-452b, along with bodies, I guess people really need a sim about it.

Don't be confused by the name on the top and bottom Kepler-452.
The top is the star to put in the "Bodies" folder, and the bottom is the sim to put in the "Simulations" folder.

Here's a comparison between Earth & Kepler-452b, in orbit and radius.
After all, it is the most Earth-like planet we've found so far.

BTW: The radius sim is at 0 secs per step to prevent tidal fragmentation, but if you'd like to change the timestep, and unlock the positions, you could watch Earth collide with Kepler-452b, for fun.
