A shocking fact about every planet in the solar system

A shocking fact about every planet in the solar system

Do you really know about our solar system?


The hematite spheres (or ‘Mars blueberries’) depicted by Mars Exploration Rover. These are almost certainly evidence of past liquid water on Mars, and possibly for past life. NASA scientists must be sure that this place — â € ”and this planet â € Š — â €” are not polluted by the observation itself. So far, there is no conclusive evidence of either past or present life in March.

Every world has secrets that are usually not recognized.

The northern polar noras seen on Jupiter, pictured here with Hubble’s NICMOS camera, represent a cyclotron-driven maser: the first to be discovered from a planetary body in our own solar system.

Can you identify all 10?

The surfaces of six different worlds in our solar system, from an asteroid to the moon to Venus, Mars, Titan and Earth, show a variety of properties and history. While the earth is the only known world where life arose, these other worlds may one day expand our current understanding of how often life arises.

1.) I’m the hottest planet.

clouds of Venus

WISPR data from the Parker Solar Probe, in monochrome, clearly match the surface properties seen by the infrared orbiter Magellan, shown in assigned color. Long-wavelength light, such as infrared light, can see through the clouds of Venus, all the way down to the surface. It is only because the clouds themselves radiate in the infrared that phosphine can act as an absorber along the line of sight.

The atmospheric greenhouse effect on Venus gives consistently higher temperatures than Mercury.

The surface of Venus, seen by one of the old Venera landers of the Soviet Union (most likely Venera 14): the only set of spaceships that ever managed to land and transmit data from that world. The series of Venera landers survived for between 39 minutes to about 2 hours; no longer.

2.) I am the most metallic planet.

densest planet

When it comes to the large, non-gaseous worlds of the solar system, Mercury has by far the largest metallic core in relation to its size. However, it is the earth that is the densest of all these worlds, without any other larger body comparing in density, due to the extra factor of gravity compression.

An early vapor state is ensured Mercury is ~ 75% metalin mass.

The image above shows an orthographic projection of this global mosaic centered at 0 ° N, 0 ° E. The radiated crater Debussy can be seen towards the bottom of the earth and the top ring basin Rachmaninoff can be seen towards the eastern edge. Mercury is the innermost planet in the solar system, and was mapped in detail by NASA’s MESSENGER mission.

3.) I am originally the 8th planet.

The dwarf planet Ceres, shown here, is the largest world in the asteroid belt and the only one known to be in hydrostatic equilibrium. Discovered in 1801 by Giuseppe Piazzi and originally classified as a planet: the 8th of the solar system.

Ceres, was discovered in 1801is the lone dwarf planet of the asteroid belt.

The four largest asteroids, all shown here, have been depicted using NASA’s Dawn mission and ESO’s SPHERE instruments. Ceres, the largest asteroid, is the smallest known body in hydrostatic equilibrium. Vesta and Pallas are not, but Hygeia’s status is indefinite; it may be yet.

4.) My planetary system contains the most water.

In size, it is clear that the gas giant’s worlds surpass any of the Earth’s planets. When it comes to water, however, the giant planets, due to their lunar systems, may have more water than even the planet earth does.

It’s Jupiter, whose moons Ganymede, Callisto and Europe individually have more water than the earth.

Although the earth contains the most liquid water on its surface of any of the 8 planets, there is the most water in any form on Jupiter’s moon Ganymede. Next in line are Saturn’s Titan, Jupiter’s Callisto and Jupiter’s Europe. Planet Earth has only the 5th most water, which places it ahead of Pluto, Dione, Triton and Enceladus.

5.) I am the most massive object coming from the Kuiper Belt.

Triton’s south polar terrain, as photographed by the spacecraft Voyager 2 and mapped into a spheroid of suitable shape and size. About 50 dark plumes mark what are believed to be cryovolcanoes, with these traces caused by the phenomenon known in everyday speech as “black smokers”.

Captured Moon, Tritonsurpasses Pluto and Eris in both mass and size.

When you rank all the moons, small planets and dwarf planets in our solar system, you discover that Triton, the 7th largest moon, has more similarities with Pluto than it has with anything else in the solar system. Triton is larger and more massive than both Eris and Pluto, and also comes from the Kuiper Belt. At one point it was the true “king” of the Kuiper Belt.

6.) I am the planet with the lowest density.


When we classify the known exoplanets by both mass and radius together, the data indicate that there are only three classes of planets: terrestrial / rocky, with a volatile gas envelope but no self-compression, and with a volatile envelope and with self-compression. Everything above it is a star. The planet’s size reaches a peak with a mass between Saturn and Jupiter, with heavier and heavier worlds becoming smaller until real nuclear fusion ignites and a star is born. Saturn is almost the lowest density planet out there.

At 0.687 g / cm³ is Saturn the only planet less dense than water.

Saturn, as photographed here by Cassini during the 2008 equinox, is not only round, but is in hydrostatic equilibrium. With its low density and fast rotation, Saturn is the most flattened planet in the solar system, with an equatorial diameter that is more than 10% larger than its polar diameter.

7.) I have the strongest winds.

These images of Neptune, from October 7, 2017 with the Hubble Space Telescope, show the presence of clouds, bands and varying colors and temperatures over Neptune’s upper atmosphere. The rapid changes reveal Neptune’s wind speeds: the fastest in the solar system.

(Credit: ESA / Hubble and NASA, acknowledgment: Judy Schmidt)

With speeds above 1,100 mph (492 m / s), Neptune’s winds are unsurpassed.

Although Neptune, through the Galle telescope at the Berlin Observatory, appeared only as a small, faint, blue disk, it did not appear on previously recorded sketches of just that part of the sky, which d’Arrest suggested. On September 23, 1846, the 8th planet was discovered in our solar system, Neptune.

8.) My fragments pollute the earth.


This scanning electron microscope image of a fragment of the Allen Hills 84001 meteorite contains inclusions that resemble the simple life that exists on Earth. Although this test is completely incomplete, bombardment of the earth with extraterrestrial objects is a security. If they contain dormant or fossilized life, we can detect it via this method.

It’s Mars; 3% of all terrestrial meteorites derive from there.

Winds with speeds up to 100 km / h travel over the surface of Mars. The craters in this image, caused by impact in Mars’ past, all show different degrees of erosion. Some still have defined outer rims and clear features within them, while others are much more flexible and distinctive, evidence of old age and erosion. On Earth, 3% of our meteorites come from Mars; it is unknown how much of the Martian influence originates from terrestrial rocks and whether life has been stored away on any of them.

9.) I change most from the solstice to the equinox.


Infrared images of Uranus (1.6 and 2.2 microns) obtained on August 6, 2014, with adaptive optics on the 10-meter Keck telescope. The white spot is an extremely large storm that was brighter than any trait ever recorded on the planet in the 2.2-micron band. The cloud that rotated in sight at the lower right part grew into a storm that was so large that it was visible even to amateur astronomers at visible wavelengths. These features did not exist in 1986, when Voyager 2 flew past Uranus.

It is Uranus, whose 97 ° axial inclination causes planet-wide changes every 21 years.


Although this is a modern, infrared view of the seventh planet of our solar system, it was first discovered in 1781 through William Herschel’s serendipital observations. Until the advent of space telescopes and infrared astronomy, we had no idea that Uranus was ever anything but dysfunctional.

10.) I am the last planet to form.

An illustration of what a synestia might look like: an inflated ring that surrounds a planet after a high energy, large momentum impulse. This probably represents the aftermath of the collision that resulted in the formation of our moon. Although our planet has remained intact since then, an impact with comet Bernardinelli-Bernstein can create a similar phenomenon.

(Credit: Sarah Stewart / UC Davis / NASA)

It is us! An impact 50 million years after the formation of the other planets created today’s Earth-Moon system.

Japan’s Kaguya probe orbited the moon, enabling magnificent views of the earth seen over the moon’s surface. Here, the Moon is photographed along its day / night boundary, the terminator, while the earth appears in a half-full phase. From the near side of the moon, the earth is always visible; both are the result of the aftermath of an early, giant impact between a Mars-sized protoplanet and a proto-Earth.
