Earth Type Planet found

NASA discovers Earth-like planet in ‘habitable zone’

NASA astronomers announced Thursday that they had found an Earth-like planet roughly 1,400 light years away.

he newly discovered Kepler-452b, which is in the Cygnus constellation, orbits a star from what is called the habitable zone: the distance at which water can pool on the surface of a planet.

Other planets, such as Kepler-186f, have been discovered in this sweet Goldilocks spot that is neither too close nor too far to potentially sustain life.

But Kepler-452b is different because it circles a G2-type star — just like our sun.

How they figured out ways to wring a bunch more science out of Kepler via the K2 mission is pretty damn cool.

Problem is it's twice as massive as earth, so if you don't want to weigh 300 lbs, don't go there.

It's estimated to have 1.6 times Earth's radius. If the density is the same that would mean it has 1.6 times the gravitational attraction (I can show the math if you're interested)

But that's only true if the density is the same. I don't know how much variability is plausible, but while Mercury, Venus, and Earth have similar density Mars is substantially less dense (about 71% Earth's density). If it has a Mars-like density then the gravitational attraction would be a mere 1.14x Earth's which is pretty negligible.

i heard ancient aliens created a wormhole interstate between different parts of the universe. i'm sure the secret space program knows how to use it.

Better start squatting, nerds.

The models are showing it to be about twice as massive as Earth, giving it twice the gravity. http://www.cnn.com/2015/07/23/us/feat-nasa-kepler-planet-discovery/

A visitor there would experience gravity about twice that of Earth's, and planetary scientists say the odds of it having a rocky surface are "better than even."

Let's play Excel spreadsheet, boys!

1 Light Year = 9.4 Trillion Kilometers.
This "Earth Type Planet" is 1,400 light years. Hold onto your !@#es.

Voyager 1 spacecraft is traveling at a speed of:
Second: 17.26 km
Minute: 1,035.6 km
Hour: 62,136 km
Day: 1,491,264 km
Year: 544,311,360 km

To reach your destination... at over 17km/s.
1 Light Year: 17,381 years.
Nearest Star: 73,697 years.
"Earth Type Planet": 24,334,234 years.

Good luck.

Juno is (was? Don't know if it still is) travelling 25 miles per second, which is 40.23 km/s.

Presumably it is possible to travel even faster than that with existing technology. Surely something that would hold people would travel faster than that.

1,268,806,809.6 km/year, so a measly 10,371,949 years at the speed of Juno!

only take 2400 years to find out I hear.

monocellular organisms shouldn't be too much influenced by gravity right?

If so, I wonder what kind of multicellular organisms could develop with such a high gravity.

They are affected by gravity...in fact very much so. In that high of gravity, multi-cellular life would probably be a bit more short, stocky, and possibly have several legs to hold up their body mass.

It's a trap!
