It is unlikely that life as we know it could survive on Mercury due to solar radiation, and extreme temperatures. Standing on Mercury's surface at its closest approach to the Sun, our star would appear more than three times larger than it does on Earth.
The smallest planet in our solar system has a big presence in our collective imagination. Scores of science fiction writers have been inspired by Mercury, including Isaac Asimov, C. Lewis, Ray Bradbury, Arthur C. Clarke, and H. Television and film writers, too, have found the planet an ideal location for storytelling. In the animated television show "Invader Zim," Mercury is turned into a prototype giant spaceship by the extinct Martians. In the comic strip "Calvin and Hobbes," Calvin and his classmate Susie give a presentation about Mercury, in which Calvin's contribution is full of questionable information: "The planet Mercury was named after a Roman god with winged feet," says Calvin.
Why they named a planet after this guy, I can't imagine. Mercury is the smallest planet in our solar system. Venus is hotter. Along with Venus, Earth, and Mars, Mercury is one of the rocky planets.
It has a solid surface that is covered with craters like our Moon. In those shadows, it could be cold enough to preserve water ice despite the high temperatures on sunlit parts of the planet. Instead of an atmosphere, Mercury possesses a thin exosphere made up of atoms blasted off the surface by the solar wind and striking meteoroids. Mercury's exosphere is composed mostly of oxygen, sodium, hydrogen, helium, and potassium. Mercury's magnetic field is offset relative to the planet's equator.
When the ions strike the surface, they knock off neutrally charged atoms and send them on a loop high into the sky. Mercury Poster. Introduction The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth's Moon. Namesake Namesake Mercury is appropriately named for the swiftest of the ancient Roman gods.
Potential for Life Potential for Life Mercury's environment is not conducive to life as we know it. A 3D model of Mercury, the innermost planet. JPL's lucky peanuts are an unofficial tradition at big mission events. Full Moon Guide: October - November A new paper details how the hydrological cycle of the now-dry lake at Jezero Crater is more complicated than originally thought.
The lander cleared enough dust from one solar panel to keep its seismometer on through the summer, allowing scientists to study three big quakes. This year, the minimum extent of Arctic sea ice dropped to 1. Researchers will use Webb to observe 17 actively forming planetary systems. Scientists found evidence that an area on Mars called Arabia Terra had thousands of "super eruptions" over a million-year period. Perseverance successfully collected its first pair of rock samples, and scientists already are gaining new insights into the region.
But what type of planet is Mercury? Mercury is classified as a terrestrial planet. So the terrestrial planets are similar to Earth. For example, the average density of Mercury is 5. Mercury only has one sunrise every Earth days! Isn't that weird?
