First potentially habitable Earth-size planet discovered by TESS mission, and it's nearby

Source: CNN

NASA's planet-hunting mission TESS has found its first potentially habitable exoplanet the size of Earth orbiting a star about 100 light-years from Earth, according to the agency.

The findings were announced during the 235th meeting of the American Astronomical Society on Monday in Honolulu.

The planet is part of a multi-planet system around TOI 700, a small, cool M-dwarf star in the Dorado constellation. It's only about 40% of our sun's mass and size, with half of the surface temperature.

The planet is known as TOI 700 d, one of three orbiting the star. It's at just the right distance to support liquid water on the surface in the star's habitable zone.

"... about 100 light-years from Earth"

You'd have to travel at the speed of light (186,282 miles per second) for 100 years to get there.

Nearby?

Some stars are millions or even billions of light years away.

(from the perspective of the traveler of course)

((but that's not factoring in the human limitations and subsequent overhead of both acceleration and de-acceleration -- after all we don't want to arrive squashed))

We may only be able to reach about 20% of the speed of light, if we can solve some nearly insurmountable challenges. So it would take that ship 500 years to get there, and then it somehow needs to stop. And that's if there is nothing between us and them.

But hey, it's not 1000 light years away, right?

Yeah, yeah, worm holes. I seem to have misplaced mine. Anyone know where it went?

It's still interesting. I love this shit. I need to be abducted by aliens; it's on my bucket list........

Our ark travelers arrive there in 100-500 years and tell whomever is there,"congratulations, we're your new neighbors." But we're unfortunately not welcomed, so our folks naturally turn around and go home...... Not!

Let's send the best of humanity there, we need a planet 'B'!

First thing to do, once they get there, is to shake the hibernation stiffness out of their limbs, and go and decimate the native populations!

They are probably building a space wall as we speak.

And we will be presented a bill for it when we get there.

Humans will never travel to that planet. And if they did, who can say whether the current inhabitants would welcome them? We can't plan the future by setting goals that cannot be accomplished. We would do far better to solve our own problems here.

There is no Planet B.
