NASA is actively working on asteroid defense, alleviating fears of catastrophic impacts by intercepting potential threats to Earth.

Multiple asteroids safely passed near Earth on Thursday, highlighting the ongoing need for surveillance of potentially hazardous space rocks.

Astronomers are studying near-Earth asteroids for future impact prevention, reinforced by a recent close approach of three asteroids.

A second mini-moon, asteroid 2024 PT5, will briefly orbit Earth beginning September 29 before escaping its gravitational pull.

Asteroid 2024 ON is a peanut-shaped contact binary, highlighting the diversity of shapes in near-Earth asteroids.

X-ray technology may provide a method for deflecting asteroids, enhancing planetary defense.

Two meteor showers from ancient debris are peaking, offering a rare opportunity for skywatchers to witness them this week.

The Perseid meteor shower will peak overnight from Sunday to Monday in California, offering a dark sky for spectators.

Meteors come from comets and asteroids, disintegrating as Earth passes through them annually, creating shooting stars.

The Perseid meteor shower reaches its peak in mid-August, providing a chance to see 50-75 shower members per hour in rural locations.

Asteroids and comets formed 4.5 billion years ago, with varied orbit patterns ranging from few years to thousands or even millions of years.

Most meteorites on Earth originate from three recent asteroid collisions.

A newly discovered mini moon, asteroid 2024 PT5, will temporarily orbit Earth for about two months before departing into space.

2024 PT5 is a newly identified mini moon expected to orbit Earth temporarily for two months. It exemplifies the chaotic dynamics of mini moons.

Astrotourism is rising with travelers planning trips around celestial events, highlighting increasing interest in astronomy.

Earth will have a temporary mini-moon, asteroid 2024 PT5, for 57 days starting September 29, 2024.

Earth will have a temporary second moon, an asteroid named 2024 PT5, from September 29 to November 25, 2023.

Hera's mission aims to gather critical data on asteroid deflection efforts following NASA's DART impact, potentially safeguarding Earth from future asteroid threats.

Asteroid 2024 ON, despite being labeled potentially hazardous, passed Earth safely and highlighted misconceptions about near-Earth object risks.

Planetary defense against asteroids is a serious and pressing issue, requiring global collaboration to prevent potential catastrophic impacts.

Asteroids could serve as a potential food source for astronauts by converting their material into nutritional biomass using bacteria.

Asteroids are key to understanding the early solar system and preparing for potential future impacts.

The European Space Agency's Gaia mission discovered hundreds of potential moons orbiting over 350 previously unknown asteroids, providing insights into the solar system's formation and evolution.

Earth may have had a ring of asteroid debris 466 million years ago, evidenced by meteor craters lining the ancient equator.

The asteroid that killed the dinosaurs was 10 km in diameter, while the impactor that formed the Moon may have been the size of Mars.

Scientists at the American Geophysical Union meeting discussed how asteroids shaped Earth, causing melted rock and ancient tsunamis.

Marchi and colleagues used the Moon to estimate the number of asteroids that collided with Earth.

A massive asteroid impact 4 billion years ago shifted Ganymede's axis, more profoundly than the dinosaur-extincting impact on Earth.

Water molecules have been discovered on the surface of asteroids for the first time.

The presence of water on asteroids can provide valuable insight into the distribution of water in our solar system and the potential for extraterrestrial life.
