How High Does Mount Everest Rank In The Solar System? Where Is The Tallest Mountain In The Solar System?
The so-called gravitational equilibrium surface refers to the surface formed by the same point of gravity. On Earth, we call the gravitational equilibrium surface that coincides with the stationary ocean surface the "geodetic level", which is actually equivalent to what we often call sea level.

Nasa Finds Junk On Mars When It's Clearly Empty: A Shiny Piece Of Metal Embedded Between Rocks
So far, we have not found any trace of life on Mars. No one knows whether there is life on Mars. However, when we are exploring Mars, sometimes we will see some interesting scenes, even some garbage. It is strange that there is no one on Mars. Why is there garbage? Where does this rubbish come from?

New 'Extraterrestrial Home' Discovered? Scientists: Dense Atmosphere, Likely Life
Like Earth, Titan has a nitrogen-rich atmosphere, with 98.44% of its atmosphere being nitrogen, making it the only nitrogen-rich planet in the solar system other than Earth.

How Long Does It Take For The Sun To Travel 792,000 Kilometres Per Hour And Make a Full Revolution Around The Centre Of The Milky Way Galaxy?
In the Milky Way, the closest stars to the Sun are 4.22 light years away

What Would Happen If You Fired a Shot At The Moon From The Space Station? Would It Hit The Moon?
If a shot is fired at the moon from the space station, the bullet fired will be firmly bound by the earth's gravity and it will be impossible to hit the moon

Another Potentially Habitable Planet Has Been Discovered, And The Only Thing Scientists Are Worried About Is The Possibility Of Alien Life
This exoplanet, known as TOI 700d, is about 101.5 light years away from our Earth, which means that even if we were to travel to this exoplanet in a light-speed spacecraft, it would take at least 101.5 years of flight to reach it, so it is very far away

Is There Really Water On Mars? Scientists Have Debated For Decades After Rover Photographed An Avalanche On Mars
Data returned by the Odyssey Mars Rover suggest that these slope streaks are generally found on the sides of hills and mountains in Martian craters, and that their formation may be caused by frost formed by carbon dioxide at low temperatures

The Secret Of The Centre Of The Milky Way Is About To Be Revealed And The Eht Will Announce a Major Discovery On 12 May
Ever since humans began to look up at the stars, they have been curious about the vastness of the universe, and this is still the case today. With the help of various observation devices, modern humans can take a large number of photos of the deep space of the universe, which are updated almost every day.

Having Flown 23 Billion Kilometers, This Photo Of Voyager 1 Is Thought-Provoking: Is Earth a "Zoo"?
At the time of the "family photo" of the solar system, the Voyager 1 probe has reached a distance of 6.4 billion kilometers from Earth, very distant, so in the view of the Voyager 1 probe, the solar system, the major celestial bodies are very small

What Is So Special About Gliese 581g, Thought To Be The Most Earth-Like Exoplanet Known?
It has been billions of years since life appeared on earth, and although there are seven planets in our solar system in addition to earth, as well as a number of dwarf planets, moons and other relatively large bodies, so far we have not found alien life on any other planet in our solar system for the time being. Even mars, another earth-like planet in the habitable zone of our solar system, has not found a single sign of life. Could it be that life on earth is really unique and no other planet is allowed to have life?
