To understand the porosity, astronomers studied the surface temperature of the asteroid. According to astronomers, the asteroid surface is about 50 per cent porous and was formed by the cosmic debris and dust by the collision of large space junk. He says that the porous, fragile asteroids like Ryugu could be the missing link in understanding how the cosmic dust evolves into massive celestial bodies. According to the researchers, the details from the asteroid samples could significantly alter the current timeline of planet formation in the solar system.Īstronomer Matthias Grott from the DLR Institute of Planetary Research is one of the authors of the study. The spacecraft is scheduled to re-enter Earth by the end of 2020 and will land in Australia. The Hayabusa 2 was designated to map the asteroid in orbit and then land to collect samples from its surface. But Japan’s space mission Hayabusa2 has revealed that the carbon-rich asteroid Ryugu’s surface is porous and light, thus throwing in new details into the theories on the formation of celestial bodies. A new study, published in Nature on Monday, highlights the nature of this primitive asteroid.Īsteroids are generally assumed to be as a hard rock material, with rough surface texture. Now, a peculiar feature of this massive asteroid-measuring one kilometre in diameter-is likely to open new avenues of research in understanding the solar system further.
Most of these space rubble orbit the Sun and one such near-Earth object is an asteroid named 162173 Ryugu. Cosmic dust, meteorites, and asteroids floating around the solar system form important evidence in understanding the early history of the solar system. The solar system-home to our planet Earth-formed around 4.5 billion years ago.
