Most extreme temperature fluctuation Though mercury is the closest to the sun still it is the second most hottest planet of our solar system , but it does have the most extreme temperature fluctuations in the solar system. The temperature during the day can reach 840 degrees Fahrenheit (450 degrees Celsius), but at night, temperatures can get as low as minus 275 F (minus 170 C). That equals to a temperature difference of more than 1,100 F (600 C), the largest of any planet in the solar system. 2. Mercury has water ice and organic compounds This may sound surprising given that the planet is so close to the Sun, but the ice is in permanently shadowed craters that don’t receive any sunlight. Organics, a building block for life, were also found on the planet’s surface. While Mercury doesn’t have enough atmosphere and is too hot for life as we know it, finding organics there demonstrates how those compounds were distributed throughout the solar system. There’s also quite a bit of sulfur
Ever thought of if we made contact with other intelligent life form , how are we gonna meet them physically with all the humans on earth? Don't worry there is a solution , and it is "Stellar Engine". Now what is a stellar engine? Simply put it is a hypothetical megastructure which uses a star's energy to propel or move the star and as the star moves the other planets will also move due the gravity of the star. The concept of Stellar engine was first introduced by Badescu and Cathcart. There are three classes of stellar engines : 1.Class A - Shkadov thruster One of the simplest examples of a stellar engine is the Shkadov thruster, or a Class A stellar engine. Such an engine is a stellar propulsion system, consisting of an enormous mirror/light sail—actually a massive type of solar statite large enough to classify as a megastructure—which would balance gravitational attraction towards and radiation pressure away from the star. Since the radiation pressure of the star wo
