Green Comet C/2024 E1 Brightens Near Mars as Scientists Forecast a Permanent Exit From the Solar System
Astronomers are closely tracking the bright green comet C/2024 E1 as it approaches Earth and prepares for a future escape from the solar system. Originating from the distant Oort Cloud, the city-sized comet is on a hyperbolic path and is expected to be permanently ejected after its close solar encounter, similar to the interstellar object 3I/ATLAS.

Interstellar Comet 3I/ATLAS: NASA-Approved Answers To 10 FAQs
NASA mentioned that the Interstellar Comet 3I/ATLAS has been approaching from the general direction of the constellation Sagittarius.

Interstellar Comet 3I/ATLAS Nears Earth on Dec. 19, Offering Rare Insights Into Cosmic Visitors
Interstellar comet 3I/ATLAS will make its closest approach to Earth on Dec. 19. Observing the comet provides scientists a rare opportunity to study dust and gases from its icy nucleus and learn more about material forming around other stars, expanding understanding of interstellar objects while posing no threat to our planet.

Interstellar Comet 3I/ATLAS Turns Green Ahead Of Closest Approach To Earth
3I/ATLAS has offered scientists a unique opportunity to study material formed around another star.

A Nearby Planet May Have Formed the Moon Following a Collision With Early Earth: Study
A new analysis of Apollo samples and Earth rocks suggests that a nearby rocky planet, not a distant object, collided with early Earth and formed the moon. The study argues that this lost planet, Theia, originated in the inner solar system and shared Earth’s early neighbourhood, offering fresh insight into one of the most important events in our p...

New Study Models How Interstellar Objects Could Approach and Impact Earth
A new study simulating billions of hypothetical interstellar objects finds that potential Earth-crossing bodies would most likely arrive from the solar apex and the galactic plane. The research highlights relative approach patterns rather than predicting real impacts. Scientists emphasise that known visitors like ‘Oumuamua and Borisov pose no dan...

Two Large Bus-Sized Asteroids To Pass Earth This Week
According to CNEOS manager Paul Chodas, "potentially hazardous" doesn't mean an asteroid is going to collide directly with Earth.

Rising Satellite Traffic in Low Earth Orbit Sparks Collision Risk Concerns
A new study in Acta Astronautica warns that Low Earth Orbit is becoming dangerously congested. Since 2019, the number of satellites performing more than ten collision-avoidance maneuvers per month has risen sevenfold. With nearly 25,000 tracked objects and more launches planned, scientists fear a chain-reaction risk and call for stronger global coo...

New 'Quasi-Moon' Discovered in Earth Orbit May Have Been Hiding There for Decades
Astronomers have identified asteroid 2025 PN7 as a possible quasi-moon of Earth, trailing our planet for nearly 70 years. At just 62 feet wide, it is the smallest and least stable quasi-satellite detected so far. Researchers believe advanced observatories like the Vera Rubin Observatory could uncover more hidden companions in Earth-like orbits

'City-Killer' Asteroid May Hit Moon, Hurl Deadly Debris Toward Earth
Asteroid 2024 YR4 might collide with the Moon in 2031, with a 4.3% chance of impact, according to NASA's updated calculations.

Study Reveals Earth's Small Asteroid Likely Originated from the Moon
Asteroid 2024 PT5, discovered near Earth in 2024, is suspected to be a fragment from the Moon’s surface. Researchers found its composition matches lunar rock samples, specifically silicate-rich materials, unlike any known asteroid. Analysis from NASA’s Center for Near Earth Object Studies confirmed it is a natural object, not human-made debris,...

An Asteroid Burned Up Over California Just Hours After Being Spotted
On October 22, 2024, asteroid 2024 UQ was detected just hours before entering Earth’s atmosphere over the Pacific Ocean, near California. The ATLAS survey detected it shortly before impact, but delayed tracking data prevented immediate monitoring. The European Space Agency’s Near-Earth Object Coordination Centre later confirmed the asteroid's e...

NASA’s 15-Year-Old NEOWISE Spacecraft Re-Enters Earth's Atmosphere After 15 Years in Space
NASA's NEOWISE spacecraft, originally launched as WISE in 2009, has ended its mission after nearly 15 years in operation. It successfully identified around 3,000 near-Earth objects and contributed significant data to the scientific community. NEOWISE's demise was attributed to the current solar maximum, leading to its atmospheric re-entry. As NEOWI...

Earth's Temporary Second Moon: Asteroid 2024 PT5's Two-Month Orbit Explained
Asteroid 2024 PT5 will soon become Earth’s temporary second moon, entering orbit on September 29 and departing by November 25. While this mini-moon won't complete a full orbit, it will be caught in Earth’s gravitational pull for nearly two months. Unlike other celestial objects, this asteroid will be too dim to observe without advanced equipmen...
