Hello everybody, my name is Mars. Today I will talk about space. Space have eight planets.A lot of cool facts. Today I'm going to tell you about my four favorite ones. First is Earth.The planet we live on from space. Earth look blue because it means 79% of water and 21% of land. Next is Mars.The planet I'm named after and it called a red planet because it cover rust which makes it look red. Then come Saturn. The planet has lot of rings.It have 140 more rings on Saturn and it looks really pretty. Last is Jup ...
POV: 3I/ATLAS is making its closest approach, and you need answers. 🔭

We need to talk about Comet 3I/ATLAS and its seemingly suspicious behavior. Is it possible that it’s actually something else entirely. 3I/ATLAS is only the third object detected passing through our solar system from elsewhere in the galaxy.So it’s understandable that we’re all wondering what’s going on. I went to Google Search and I asked AI Mode the question on everyone’s mind: As far as 3I/ATLAS speeding up goes, it’s called “non-gravitational acceleration. “ Basically, it’s acting like a tiny rocket.But ...

The Sun is 99.8% of all mass in our solar system.Even if you somehow burned Jupiter and everything that is not the Sun in a fusion reactor, the Sun would still round up to 100% of all energy.The Sun is all that matters long-term.Brian Roemmele (@BrianRoemmele):Behold: the reality of our relativity in the solar system. https://t.co/PAzJYoygbO ...

Space Exploration & Comet Research - A comet, traveling at 25,000 kilometers per hour, is approaching the solar system and will be targeted by the Comet Interceptor mission [1][3] - The Comet Interceptor mission, funded by the European Space Agency in collaboration with the Japanese Space Agency, aims to study a comet coming close to the sun for the first time [3][24] - Comets are believed to have delivered organics and water to Earth, crucial for the formation of life, but also pose a threat of impacts [12][13][14] - Missions to processed comets have limitations, necessitating a mission to an unchanged comet from the Oort cloud, which contains hundreds of billions or even trillions of comets [23][24][25] - The Comet Interceptor mission will park in a stable orbit, wait for a suitable comet, and then intercept it for a few hours to collect data [29][30][31][32] Planetary Defense & Space Mission Strategy - The mission aims to test the strategy of parking in space until a target is identified, which could be used for planetary defense against hazardous objects [33][34] - Developing instruments for space exploration is a time-consuming task, requiring years or even decades of rigorous testing [27] Scientific Significance - Asteroids and comets are relics from the early solar system, with asteroids forming closer to the sun and comets forming in the outer solar system [7] - Studying comets can provide insights into the materials from the outer solar system, where ice is preserved [22]
