Therefore Titan would be 9AU further away from that point. Can shareholders compel a company to not pay taxes? But the surface temperatures are very different, 94 K for Titan but the mean surface temperature of the Moon is 218 K and the peak about 300 K. Due to the high surface temperature of the Moon, a small part (due to the Bolzman distribution) of the gas atoms have a velocity bigger than the escape velocity of the Moon. why does titan have an atmosphere? So the solar wind flux reaching Titan is 9 squared or 81 times weaker than at our moon. Fedora shows / mounted at the same location as home. How many pillars do we need to surround a triangular area? Answer Save. First, it could be that because Saturn is farther out than Jupiter, Titan formed in a colder environment and had a greater amount of nitrogen-rich gases around it, and these formed the atmosphere. Titan is also much further from the Sun, making the gas particles move much more slowly so they don't escape and instead condense … Our Moon, if formed by a collision, had its volatile matter escape between the time of the collision and its re-formation into a massive body, whereas Titan retained more volatile matter. Can this be by chance? Hypothetically, the incoming solar wind bombardment also increases the kinetic energy of the gas molecules over the escape velocity so that over time an atmosphere not protected by a magnetic field would lose its atmosphere due to the … How can private businesses compel the government to collect tax? Does the Dragonfly project (quadcopters on Titan) envision attached RTG's or would they be static and revisited for charging? why does Titan have a thick atmosphere and mercury does not? If a piece of software does not specify whether it is licenced under GPL 3.0 "only" or "or-later", which variant does it "default to"? Titan itself doesn't have a magnetic field to protect it from the solar wind, but it does happen to orbit an enormous planet with a magnetic field. The second is that because Jupiter's gravity well is deeper, its moons had their atmosphere blasted off by faster-moving comets. This also explains why Titan wouldn’t have any oxygen, since this is not true for oxygen molecules as they would be broken up by this radiation. It does not have a strong enough gravity field to prevent gases, if they existed on the Moon, from escaping into space. Is it substantially less dense? The helium in the moon's atmosphere is easily lost, since it's so much lighter. Titan has an atmosphere because it is large enough to have a significant enough gravity field to prevent the gases there from escaping into space. Information from this blog and more detailed information on this subject is found in this video. Lv 7. they both have similar surface gravity but one has a thick atmosphere and the other doesn't. Use MathJax to format equations. Being that its host planet, Saturn, is 10 Astronomical Units from the sun. ( Log Out / Relevance. You are right that it's surprising that Titan, being just a moon, has a thick atmosphere. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. The chemistry of Titan's atmosphere is complex, with reactions occurring between carbon dioxide, oxygen, carbon monoxide, hydroxl, and other compounds. +1 as this is the only answer touching on the important topic of outgassing history. Think of it as the Moon having tides because of effects from the Earth, rather than vice-versa. How viscous is the liquid? So I dunno how it got an atmosphere? The gravity at the surface is 1,35 m/s² for Titan and 1,62 m/s² for the the Moon. Answer Save. ( Log Out / This also explains why Titan wouldn’t have any oxygen, since this … To what extent is grease interchangeable? Is Cassini equipped for detection of non-water-based exobiology? 6 years ago. So I dunno how it got an atmosphere? Titan has more mass but less surface gravity? Is a software open source if its source code is published by its copyright owner but cannot be used without a commercial license? Every second customer converts better. Mars How quickly might a Titan rover or drone get covered in oil and dirt? Saturn’s large moon Titan, with its smaller moon Mimas in the foreground, as seen by the Cassini spacecraft in 2013. When a planet loses atmosphere, where does it go? They both have a troposphere, stratosphere, mesosphere, and thermosphere. Titan has less gravity than Earth's moon, shouldn't it have no atmosphere? Titan also has more of the right stuff to work with, in order to make an atmosphere. 4 Answers. What would a “water” landing on Titan be like? Favorite Answer. Or are heavier elements like Methane and Nitrogen the only elements which Titan can sustain as an atmosphere?
