Things Worth Noting
3I/ATLAS (C/2025 N1) is the third confirmed interstellar comet, discovered July 1, 2025, by the ATLAS survey in Chile. Traveling on a hyperbolic trajectory with eccentricity >1, it reached perihelion at 1.4 AU on October 30, 2025, and will exit the Solar System. The 10–20 km nucleus shows strong CO₂ and CO outgassing, low water, […]
A meteor, often called a shooting star, is the bright streak of light when a meteoroid enters Earth’s atmosphere, heating to incandescence in the mesosphere at 76-100 km altitudes. Meteoroids, small rocky or metallic bodies from comets or asteroids, create this glow through friction and ablation. Surviving fragments become meteorites, classified as chondrites, achondrites, iron, […]
There is no way to predict exactly when an asteroid will hit Earth, as it largely depends on the trajectory and characteristics of any asteroids that might be on a collision course with our planet. However, scientists are constantly monitoring near-Earth asteroids and comets and studying their orbits to identify any potential impact risks. Fortunately, […]
