Titan is the largest moon of the ringed planet Solar system this.
Experts find droplets rain on Titan This is, for example, like liquid hydrocarbons that fall from the sky, then flow into river channels, and fill lakes and oceans.
However, the rain that fell on the moon Titan, as quoted from Space, Thursday (8/4/2021), in the form of Titania’s methane droplets.
While other forms of rain on the planet Venus, for example in the form of clumps of sulfuric acid and liquid helium that form rain on the planet Jupiter.
“There is a fairly small range of stable sizes found in raindrops of different compositions. They are all basically limited to the same maximum size,” said lead author Kaitlyn Loftus, a graduate student in the Department of Earth and Planetary Sciences at Harvard University.
Loftus and co-author Robin Wordsworth, professor of environmental science and engineering at Harvard, model how rain falls through the atmospheres of planets and moons of varying sizes, temperatures and compositions.
The size of raindrops on Titan and Earth
In this study, the researchers found that the maximum raindrop size does not differ much from that of most of the planets in the Solar System, whether on Earth, or on Venus, Jupiter or on Saturn’s moon Titan.
For example, the largest raindrops on Titan, Saturn’s moon, are larger than the largest raindrops on Earth.
The width of the raindrops on Titan is about 1.2 inches or 3 cm, and the largest raindrops on Earth are about 1.1 cm.
Additionally, Loftus and Wordsworth calculated that, on rocky planets, only cloud droplets of a narrow size range can eventually fall to the ground.
The cloud droplets must have a radius of between about 0.1 millimeter and a few millimeters, regardless of what material they are made of, or will not reach the surface.
The new study was published online last month at Journal of Geophysical Research: Planets.
“The insights we gain from thinking about raindrops and clouds in diverse environments are key to understanding the habitability of exoplanets,” Wordsworth said in a separate statement.
The researchers added that in the long term, looking at the raindrops on Titan, Saturn’s largest moon, could also help them gain a deeper understanding of Earth’s climate itself.
