Mini-Moon Leaves Earth Soon, Next Appearance in 2055

Earth is set to temporarily host a “mini-moon” as the 33-foot-wide asteroid 2024 PT5 gets caught in its gravitational pull. From September 29 to November 25, the asteroid will orbit our planet, providing astronomers with a unique opportunity to study its size, shape, and composition. These observations will enhance our understanding of near-Earth asteroids and inform future research on similar objects. The findings were recently outlined in the non-peer-reviewed Research Notes of the American Astronomical Society. 2024 PT5 was first

Earth-Like Planet Discovery Offers Hope for Humanity’s Survival

A team of astronomers has uncovered an Earth-like planet orbiting a star located 4,000 light years away from the solar system, potentially offering insights into our distant future. The rocky planet, about the same mass as Earth, revolves around a white dwarf in the constellation Sagittarius. As our Sun enters its final stages, this planetary system offers the best hope that humans can avoid being engulfed by its red giant phase.
