If you stand on the surface your effective weight will be around 1500 lbs. Maybe not quite enough to crush your bones but you probably won't breathe very well and will end up dying in considerable pain, assuming the planet has a surface at all.

It was on NASA's website. If I remember correctly, it's NASA's STEREO B satellite (one of two) which provide a 360 view of the inner solar system and solar winds.
What made it interesting is that something seemingly crept into frame (some refer to it as "Ezekiel's Wheel," threw up a bubble, and then left.
After people noticed it happen, it was removed from NASA's website and they deboonked it through NBC.

The official explanation was, "it's no more than a trick of the light."
Essentially, it was a "reflection of Venus" that caused a glitch in the satellite. Later, they changed it from a reflection of Venus to a "reflection of Earth."

This is all from memory, so I may be sketchy on details. So to answer your question: who knows? I just think it's sort of cool and fun looking and it was something similar to what the person I responded to posted, so I just went with it. No idea what the truth may be.

On Earth, perhaps, but in a super earth? The atmosphere might be twice as thick and twice as dense, which makes for a lot of resistance. I know that you need speed and reach escape velocity, but it is also about spending the energy of your space craft where it matters.

It gives some ideas of where to point more powerful telescopes to look for life once we get them. Actually colonizing an alien biosphere is a pretty retarded idea. You're probably better off starting from scratch with a barren planet and even better off just building space habitats.

They do it for convenience. They point the telescope at a location where there are lots of stars, with no regard to distance, and harvest loads of data. You notice this particularly with the Kepler dataset, they're thousands of lightyears away.
There haven't been any complete planetary surveys of the nearby stars, aside from Proxima.

For the moment we are detecting many "super earths" and they are the easiest to confirm liquid water. We can actually find huge numbers of smaller planets but it's too hard to see their composition.
Also consider that the nature of the star helps us make predictions. Planet B of Proxima Centauri is probably not going to have an atmosphere because it's too close to its star which makes it obviously bad for life. Probably planets need to orbit a star more like the Sun so that the habitable zone is far enough away from bursts of radiation. The Great Filter might be that intelligent life needs a planet with almost the same history as Earth.

He got the name wrong. It's Proxima Centauri b. It can also be called Alpha Centauri Cb, though. In that case the "C" denotes that it orbits the third star of the Alpha Centauri system (Proxima Centauri) and the "b" indicates its the first planet discovered in the system (it starts at b and not a because a would be the star itself).

Jupiter is a gas giant with an unclear surface. They're counting the surface starting from the very beginning of the cloud deck which is as retarded as calculating Earth's surface gravity starting from the very upper parts of the atmosphere.
This planet would break our legs just trying to walk. If we could count the surface gravity properly from the actual surface and take into account the much higher atmospheric pressure and density, then it would easily be more than twice the g on here.

Sure, scientists are working on it.
>or is it one of those problems that becomes exponentially more difficult to increase the detail?
Much remates to the diffraction limit which is inversely proportional with the diameter of the optics. So it is closer to 1/x rather than exponential, but this is still very expensive. You also want a star shade placed with great accuracy and precision at a great distance. That too will drive cost.
Still, these are more engineering problems rather than fundamental science problems.

Mass of Earth = 5.97*10^24 kg
Radius of Earth = 6371 km
ρ = M/V
V = 4/3πr^3

ρ = M/(4/3πr^3)
r^3 = M/ρ*(4/3π)
r^3 = (8.6*5.97*10^24 kg)/(5510 kg/m^3)*(4.18879)
r^3 = (5.1432*10^25 kg)/(23080 kg/m^3) = 2.228423*10^21 kg/m^3
r = ∛(2.228423*10^21 kg/m^3) = 1.3062*10^7 m = 13062 km

g = GM/r^2
G = 6.67408*10^-11 m3 kg^-1 s^-2
M = 8.6*5.97*10^24 kg = 5.1432*10^25 kg

I googled "k2-18b surface gravity", got various numbers, mostly around 12 m/s^2

https://en.wikipedia.org/wiki/K2-18b : 12.43 m/s2 (no source)
https://www.space.com/alien-planet-k2-18b-surface-conditions.html : "a visitor to the world's surface would feel 37% heavier than he or she feels on Earth. (K2-18 b's higher mass is mostly offset by its greater size in this regard, because the gravitational force decreases with the square of the distance from a planet's center.)"
https://www.reddit.com/r/spaceporn/comments/18hehsw/rendered_comparison_between_earth_and_k218b/ : DMS Surface Gravity: 11.57m/s2 (1.18g)

Strangely/disturbingly, Google states 11.57m/s2 as the truth but has no direct links.
Bing fails differently: "K2-18b, an exoplanet, has a surface gravity nearly twice that of Earth" citing https://www.space.com/alien-planet-k2-18b-surface-conditions.html which in reality states what was already quoted above.
In summary, it is a mess.

I just checked the density.
2.67 +0.52 −0.47 g/cm3
So basically it is not like Earth at all. More like a Mini-Neptune that kills us the second we step on it.

r^3 = (8.6*5.97*10^24 kg)/(2670 kg/m^3)*(4.18879)
r^3 = (5.1432*10^25 kg)/(11184 kg/m^3) = 4.598712*10^21 kg/m^3
r = ∛(4.598712*10^21 kg/m^3) = 1.6629*10^7 m = 16629 km

g = (6.67408*10^-11 m^3 kg^-1 s^-2)*(5.1432*10^25 kg)/(1.6629*10^7 m)^2 = 12.4134 m/s^2
