Enigmatic former brown dwarf spotted in the solar quarter | Astronomy

WISEA J153429.75-104303.3 (WISE 1534-1043 for short) – nicknamed “The Accident” by its discoverer, citizen scientist Dan Caselden – is a cold brown, very metal-poor dwarf located about 50 light years away in the constellation Libra. This is an artist’s impression of a free-floating Y dwarf. Image credit: NASA / JPL-Caltech. As brown dwarfs age, they […]

Asteroid found in the solar system by NASA

Asteroid Vesta is the second largest asteroid in our solar system. With a diameter of about 330 miles, it orbits the sun between the planets Mars and Jupiter. Asteroids have long played a role in popular fascination with space. “Marooned off Vesta” was the first story published by American writer Isaac Asimov, the third story […]

Astronomers discover fastest orbiting asteroid in the solar system

An astronomer at the Carnegie Institution for Science has just discovered a new asteroid, and it’s the fastest orbiting asteroid in our solar system, but speed is just one of the weird attributes of space rock. Unexplored space: Astronomers are trying to keep track of nearby asteroids so that we can avoid collisions in space […]

Solar System’s fastest orbiting asteroid discovered – Orbiting the Sun in just 113 days

Asteroid with the solar system’s shortest orbital period spotted and human DNA from 7,200 years ago

An illustration of the 2021 PH27 Orbit, by Katherine Cain and Scott Sheppard, courtesy of the Carnegie Institution for Science. | carnegiescience.edu Text size: A- A + New Delhi: Scientists have discovered a new asteroid that orbits the Sun once every 113 days, making it the asteroid with the shortest known orbital period. The asteroid, […]

Meet the 2 reddest asteroids in the asteroid belt

Artist’s concept of transneptunian objects in the outer solar system. They are generally much redder than the asteroids in the main asteroid belt because they have more complex organic materials covering their surface. Could the 2 reddest asteroids in the main asteroid belt – named 203 Pompeja and 269 Justitia – come from beyond Neptune’s […]

Interstellar comets are visiting our solar system more frequently than expected

Comets other star systems, such as 2019 Borisov, visit the Sun’s vicinity more frequently than scientists had thought, a new study suggests. The study, based on data collected Borisov zipped through Earth at a distance of about 185 million miles (300 million kilometers) at the end of 2019, suggests that the deposition of comets in […]

study: Interstellar visitors outnumber solar system objects in the Oort cloud | Astronomy

The recent detection of 2I / Borisov, the first known interstellar comet to visit our solar system, implies that interstellar objects outnumber non-interstellar objects in the Oort cloud, while the reverse is true near the Sun in due to the stronger gravitational focus of the limits. objects, according to a new article by astronomers Amir […]

Comets outside our solar system could visit us often, study finds

In the past four years, astronomers have spotted two visitors to the solar system from elsewhere in the galaxy. Both have provided an abundance of data that will be studied for many years to come – and have left scientists wanting more. A new article argues that one of those guests, Comet Borisov, represents a […]
