There are also many in a region beyond Neptune called the Kuiper Belt. The solar system also contains small objects called comets. Comets are similar to asteroids, but are made of ice, dust and ...

New simulations reveal that around 1 million "macroscopic" objects from our closest stellar neighbors, the Alpha Centauri ...

The search for interstellar visitors has taken an unexpected turn. While previous discoveries like ‘Oumuamua and Comet ...

The solar system is made up of the Sun (our nearest star) and the objects that orbit around it, including planets, asteroids and comets. Planets orbit the Sun in roughly circular paths ...

NASA artist’s conception of a brown dwarf (main) and stock image of the planets in the solar system (inset). An object between 2 and 50 times the mass of Jupiter may have flown through our ...

And tantalizingly, what they found suggests that our solar system may already be flooded with visitors from the star system, which is about 4.25 light years away. These objects range from ...

The Alpha Centauri star system is approaching the sun. Two researchers have determined how many objects from there have already reached us and could reach us. At the edge of the solar system ...

New simulations reveal that around 1 million "macroscopic" objects from our closest stellar neighbors, the Alpha Centauri system, may already reside in the Oort Cloud, far from sight.
