The Solar System is the planetary system centered on the Sun, a middle-aged star whose gravity holds together planets, dwarf planets, moons, asteroids, comets, dust, and gas. It formed about 4.6 billion years ago from a collapsing cloud of gas and dust, and its present structure preserves a record of that early history. Studying it…
Planetary defense is a critical field of research and engineering dedicated to protecting Earth from the potential hazard posed by small bodies in our Solar System. By combining advanced observations, sophisticated modeling, and ambitious space missions, space agencies like NASA aim to detect, characterize, and, if necessary, deflect threatening objects before they can cause significant…
The vision of capturing an asteroid and bringing it into Earth’s orbit has fueled both scientific inquiry and science fiction alike. As humanity pushes deeper into the cosmos, the idea of harnessing near-Earth objects for exploration, resources, and planetary defense becomes ever more enticing. However, this ambitious endeavor requires an intricate interplay of physics, cutting-edge…
