The apparent size of a celestial body in the sky can be solved using simple trigonometry. Theta is the number of arc degrees in the sky that the body occupies and

Radius of the body/distance to the body = Tangent(Theta/2)

Since Jupiter is ~140,000 km at its equator and Europa orbits ~670,000 km from Jupiter

143,000/670,000=0.2134=Tangent(Theta/2)

Theta = 11.9°

For comparison, the full moon is ~0.5°, so Jupiter would appear nearly 24 times larger than the moon!

Which moon would look the brightest from the surface of Jupiter out of lo Europa Ganymede and Callisto?

Ganymede would appear the brightest from the surface of Jupiter due to its larger size and higher reflectivity compared to Europa, Callisto, and Io. Ganymede is the largest moon in the solar system and has a highly reflective icy surface, making it more luminous when viewed from Jupiter.


Why is europa the brightest moon to Jupiter as it is not the closest?

Europa is the brightest moon of Jupiter because its surface is covered in smooth ice, making it highly reflective. This icy surface reflects more sunlight compared to the other moons with darker, more cratered terrains, despite being further away from Jupiter.


What moon would look brightest from Jupiter?

Ganymede is the largest moon of Jupiter and would appear the brightest from the planet due to its size and reflectivity. Ganymede's icy surface reflects a high amount of sunlight, making it one of the brightest objects in Jupiter's sky.


What moon would look the brightest from the Jupiter surface?

Europa would appear the brightest from the surface of Jupiter due to its icy surface reflecting a significant amount of sunlight. Io may also appear bright due to its high volcanic activity, but Europa's icy surface would likely reflect more light overall.


What would Jupiter look like from Europa, one of its moons?

Jupiter would appear as a large, bright disk in the sky from Europa, with its swirling bands of clouds and the iconic Great Red Spot visible. The planet would dominate the view, appearing much larger than the Earth's moon does from our perspective.

Why would lo look the brightest then Europa Ganymede and Callisto from Jupiter's surface?

Because it's the inner most satellite and therefor closer to the surface of Jupiter. However, the difference between the other moons is not that much.

Which moon would look the brightest from the surface of Jupiter out of lo europa ganymede and callisto and why?

Ganymede would appear to be the brightest moon from the surface of Jupiter. This is because Ganymede is the largest moon in the solar system and it has a high albedo, meaning it reflects a lot of sunlight. Its larger size and reflective surface would make it appear brighter than the other moons when viewed from Jupiter.


What would people look like on Jupiter?

Two things:1. People would be very dead on Jupiter.2. You couldn't tell what people would look like because Jupiter is a gas planet . . . it has no solid surface to stand on. People would be sucked deep into Jupiter by its very large force of gravity.


Which moon would look the brighest from the surface of Jupiter?

The answer your looking for is the moon Europa. It is one of the brightest in the solar system. The problem with the question is that if you were to stand on the surface of Jupiter which is very small and considered to be metalized hydrogen because of the pressure, you would also be a part of the surface and quite unable to see anything because you would be quite dead. Even if alive, you would have to be able to see through thousands of miles of the gaseous atmosphere. See the related link for more information.


Which moon would look the brightest from the surface of Jupiter?

The moon Io would look the brightest from the surface of Jupiter because It is the nearest.


Order of brightness between Io Europa Ganymede and Callisto?

From Brightest to Dimmest: Ganymede Io Europa Callisto Use JPL's HORIZONS web ephemeris to look up apparent magnitudes of jovian satellites.


What does the land look like on jupiter?

There is no land on Jupiter as it is a gas planet. The visible "surface" is merely clouds.
