If Earth’s diameter were doubled to about 16,000 miles, the planet’s mass would increase eight times, and the force of gravity on the planet would be twice as strong.
Q. How would your present weight change if Earth had twice the mass that it does now?
Twice the mass means twice the acceleration due to gravity which will increase acceleration by the factor of 2 thus the weight will be double the time.

Q. What will happen if the Earth is bigger than the current size?
First, if the Earth is bigger that its current size, it would also gain a stronger magnetic field and greater gravitational pull because of the additional mass, and this is a bad news for us, because lifting an object would be so much difficult than ever before due to the increased pull of gravity.
Q. What if Earth existed for only 24 hours?
If we took the whole 4.6 billion years of planet Earth history and compressed it in 24 hours, meaning that the planet was born at midnight and we were at the next midnight just now, this is what we would have: 23:23 – 37 minutes to midnight (our now), Africa is formed.
Q. Would we die if the moon exploded?
The outer layers of the Sun could reach all the way to the Earth. This would slow the Moon down, sending it falling towards the Earth. As it gets closer to the Earth it would start ripping apart, before crashing into the Earth. In either case, an exploding Moon, by natural means at least, is pretty unlikely for now.
Q. Can humans breathe on Titan?
It is cold on Titan (surface temperature of about -290 degrees F). And people would need to wear respirators to breathe oxygen, since the atmosphere is mostly nitrogen. The light on Titan is a little dim, like just after a sunset here on Earth, due to the haze particles in the thick atmosphere.
Q. How long can you survive on Titan without a spacesuit?
About a minute. Very thin atmosphere of 95% Carbondioxide will kill you within just a minute. Less than a second.
Q. What planet is the best to live on besides Earth?
A 2015 review concluded that the exoplanets Kepler-62f, Kepler-186f and Kepler-442b were likely the best candidates for being potentially habitable. These are at a distance of 1,200, 490 and 1,120 light-years away, respectively.
