NASA Confirms Bus-Sized Asteroid 2026 HJ1 Safely Passing Earth Today
A 23-foot-wide asteroid named 2026 HJ1, roughly bus-sized, is making its closest approach to Earth on April 21, 2026, at about 400,000 miles away, posing no impact risk. Astronomers are tracking it with specialized telescopes as part of routine planetary defense efforts.
This near-Earth object follows an elliptical orbit influenced by gravitational forces from the Sun and planets.
Small Near-Earth Asteroids Like 2026 HJ1 Common and Harmless, Experts Say
Asteroid 2026 HJ1 belongs to small near-Earth objects that frequently pass through Earth's orbital neighborhood without threat. Earth experiences several such close approaches monthly, most unnoticed due to their size.
If one entered the atmosphere, it would likely burn up from frictional heating.
Extreme Climate Events Linked to Higher Heart Disease Risk in China Study
A new study reveals extreme heat, cold, and precipitation events increase cardiovascular disease prevalence among middle-aged and older adults in 157 Chinese cities. Researchers used spatial econometric methods and data from 2015–2020 surveys to confirm the risks vary by city climate and location.
Findings urge targeted policies like green spaces and better infrastructure.
Study Validates Individual Exposure to Extreme Weather Boosts CVD Risk
