Biggest Asteroids to Have Close Encounters With Earth in 2023
Scientists have identified more than 30,000 near-Earth objects (NEOs) to date. So what are the largest "potentially hazardous" NEOs predicted to have a close encounter with Earth in 2023?
Some NEOs are classified as "potentially hazardous"—a designation given to those with orbits that come within 0.05 astronomical units (around 4.6 million miles) of Earth's path around the sun and are estimated to measure more than 140 meters (around 460 feet) in diameter.
A New Simulator That Determines the Impact of an Asteroid on Our Planet — Transcontinental ...
UNITED STATES: Asteroids are celestial bodies that move in space just like planets and other cosmic bodies, but the difference is the velocity with which they move.
The velocity is so high that even minor asteroids can create havoc because of the momentum they possess.
Looking Back at Big NASA Missions in 2022
The American space agency NASA announced several major mission successes in 2022. Today, we look back at some of the agency's biggest developments in the past year.
NASA announced in October that its experiment to crash a spacecraft into an asteroid had successfully changed the path of the orbiting object. Officials said it was the first time in history that a human action had changed the motion of a space object.
Here's a Calendar of 2023's Space and Astronomy Events - The New York Times
The New York Times has offered this calendar to readers since 2017. It is a collection of newsworthy events in spaceflight and astronomy curated by the paper's journalists.
It will be updated regularly to adjust dates and revise information in its entries. New events will be added and entries will be removed after they conclude or are indefinitely postponed.
Look up in 2023 for these don't miss events
A rare annular eclipse, occultations, conjunctions, and a pair of don't miss meteor showers are among the astronomical sights to look out for in 2023. NASA and other space agencies also have a list of robotic and human space exploration missions lined up for launch in the new year.
NASA's NEO Surveyor Will Defend Earth Against 'Invisible' Threats From Space - The ...
Welcome to this week’s installment of The Intelligence Brief… in recent days, we have learned about NASA’s latest efforts to ramp up planetary defense efforts by placing a next-generation telescope into orbit that will hunt for “dark” asteroids and comets.
“Sooner or later, we will face a catastrophic threat from space. Of all the possible threats, only a gigantic asteroid hit can destroy the entire planet. If we prepare now, we better our odds of survival. The dinosaurs never knew what hit them.”

Happy New Year! On Wednesday, our home planet will be at its closest distance to the sun — just 91.4 million miles, in contrast to Earth's average distance of 93.0 million miles and its farthest distance of 94.5 million miles in early July.
A look ahead at 2023 space exploration milestones
Here are the top space exploration milestones you can look forward to in 2023, including new rockets, moon missions, astronaut launches and many more planetary and Earth science objectives.
If you think 2023's schedule of rocket launches, Earth science missions and space discoveries can't possibly be as jam-packed as 2022, think again.
