@jankroon9306 Earth's circumference (the distance all the way around the equator) is 40,075 kilometers. Its diameter (the distance from one side to the other through Earth's center) is about 12,756 kilometers.

Welcome!

Indeed, the Asteroid Belt has the potential to serve as a resource hub for humanity's future space exploration and expansion.

The landing on the asteroid Eros was not part of the original mission plan but became a carefully executed final maneuver.

Ceres is no longer considered the largest asteroid because, in 2006, the International Astronomical Union categorized it as the only dwarf planet in the Asteroid belt. Watch the full episode to learn why: kzbin.info/www/bejne/hqPVdGB7qb6Xbqssi=EBRh7BUpd2Y522wh.

Thank you for the intriguing question. The Late Heavy Bombardment (LHB) is thought to have been caused by the "Nice model", a theory proposed in the early 2000s (en.wikipedia.org/wiki/Nice_model). According to this model, the LHB occurred due to the migration of the giant planets in the early Solar System. During the LHB, the Asteroid belt experienced significant disruption, scattering some asteroids inward toward the terrestrial planets. The idea of an external event, like a nearby massive star passing by or a supernova, triggering the LHB is interesting and would certainly have had the potential to disturb our Solar System’s structure. A passing star would leave detectable clues, such as noticeable alterations in the orbits of the giant planets or outer Solar System bodies, which we do not observe in present-day orbital configurations. A supernova could perturb smaller, dust-like particles in our system, but as the shockwave disperses over a vast distance it loses the momentum needed to directly alter the orbits of larger bodies in the Asteroid belt.

@ well a lot could of happened between now and then is all. I wouldn’t be so quick to accept hypocrisy ter moved in and Neptune pulled it out. (Just doesn’t seem acceptable, not to mention. Do we or will we know? Plausible is always the key to just another possibility

Many comets and some asteroids contain significant amounts of water in the form of ice. The icy interiors of these bodies are insulated by a layer of rock or dust, which can help protect the water from the intense heat generated during entry. The outer layers may vaporize or melt, but the inner ice could remain intact.

Yes, the two magnetic poles of the Earth move independently of each other. The concept of a "magnetic pole running through the Earth from top to bottom" oversimplifies the situation because Earth's magnetic field is more complex, resembling a dipole field but with significant distortions. Earth's magnetic field is generated by the motion of molten iron in the outer core, which is dynamic and not perfectly symmetrical. This means that the magnetic poles do not necessarily align perfectly with each other or with the geographic poles.

Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union.

Thanks!
