Is Europa bigger than Jupiter?

Size: Of Jupiter’s 16 known satellites, Europa is sixth in proximity and is Jupiter’s fourth largest — slightly smaller than Earth’s Moon. Orbit: Europa orbits Jupiter at an approximate 671,000 kilometer distance.

Is Europa bigger than Pluto?

With a diameter of 1,940 miles (3,100 km), Europa is the fourth-largest of Jupiter’s 79 known moons, a bit smaller than Earth’s moon but bigger than the dwarf planet Pluto.

What is the mass of Triton in KG?

triton mass
Numerical value	5.007 356 7446 x 10–27 kg
Standard uncertainty	0.000 000 0015 x 10–27 kg
Relative standard uncertainty	3.0 x 10–10

How many Earths can fit in Europa?

Edit. Europa is 3,122 km (0.246 Earths) across.

Is Titan or Europa bigger?

Europa is smaller than Titan, 3000 km in diameter versus 5000. But two other Jupiter’s moons (Ganimede and Callisto) indeed are of the same size as Titan and have no significant atmosphere.

Is there liquid water on Europa?

From ground-based telescopes, scientists knew that Europa’s surface is mostly water ice, and scientists have found strong evidence that beneath the ice crust is an ocean of liquid water or slushy ice.

Can we land on Europa?

One calculated trajectory would see a launch aboard SLS in 2025, Earth gravity assist in 2027, and Jupiter/Europa arrival in 2030. It would spend some time orbiting around Jupiter over the next year to maneuver for its landing on Europa. The landing would be performed two years after orbit insertion around Jupiter.

Is Titan bigger than Earth?

Because Titan is less massive than Earth, its gravity doesn’t hold onto its gaseous envelope as tightly, so the atmosphere extends to an altitude 10 times higher than Earth’s—nearly 370 miles (600 kilometers) into space.

Which planet has water?

But Earth is the only known planet (or moon) to have consistent, stable bodies of liquid water on its surface. In our solar system, Earth orbits around the sun in an area called the habitable zone.

Which planet has the largest ocean?

Structure. The composition of Jupiter is similar to that of the Sun – mostly hydrogen and helium. Deep in the atmosphere, pressure and temperature increase, compressing the hydrogen gas into a liquid. This gives Jupiter the largest ocean in the solar system – an ocean made of hydrogen instead of water.

Is Pluto bigger than Triton?

Then there’s Neptune’s moon Triton, a body 40 percent larger than Pluto that travels in a retrograde orbit–in the opposite direction of all the planets and major satellites in the solar system.

Why is it called Triton?

How Triton Got its Name. Triton is named after the son of Poseidon (the Greek god comparable to the Roman Neptune). Until the discovery of the second moon Nereid in 1949, Triton was commonly known as simply “the satellite of Neptune.”

Can anything live Europa?

Europa’s surface is blasted by radiation from Jupiter. That’s a bad thing for life on the surface – it couldn’t survive.

Can we walk on Europa?

Because of this, Europa, like Earth’s moon, has no weather, wind or sky colors. And walking on Europa would feel similar to walking on Earth’s moon. If you went for a stroll, you’d probably want to visit Europa’s “chaos terrain,” where the normally flat ice has been fragmented into jumbled blocks.

Could Europa have fish?

That amount of oxygen would be enough to support more than just microscopic life-forms: At least three million tons of fishlike creatures could theoretically live and breathe on Europa, said study author Richard Greenberg of the University of Arizona in Tucson.

What is the mass of Europa?

How much more water is Europa than Earth?

Scientists are almost certain that hidden beneath the icy surface of Europa is a saltwater ocean thought to contain about twice as much water as Earth’s global ocean. It may be the most promising place in our solar system to find present-day environments suitable for some form of life beyond Earth.

Can humans survive on Europa?

The type of life that might inhabit Europa likely would not be powered by photosynthesis – but by chemical reactions. Europa’s surface is blasted by radiation from Jupiter. That’s a bad thing for life on the surface – it couldn’t survive.

Can humans land on Europa?

Europa, the fourth-largest moon of Jupiter, is a subject in both science fiction and scientific speculation for future human colonization. Europa’s geophysical features, including a possible subglacial water ocean, make it a possibility that human life could be sustained on or beneath the surface.
