Asteroid Ryugu May Predate Solar System's Building Blocks
· Confirmed
In Short: Researchers studying asteroid Ryugu have found evidence suggesting it may have formed before the chondrules, which are believed to be among the earliest building blocks of the solar system, according to a report in Scientific American.

Universe Today notes that while most asteroids are found in the main asteroid belt between Mars and Jupiter, Ryugu stands out due to its age and composition.
Starlust adds that while white dwarfs typically tear apart asteroids and moons, the complexity of the system around J1328−1450 intrigued scientists, indicating unique planetary formation processes.
Sci reports on another asteroid, (44) Nysa, which has a unique three-lobed structure and a newly discovered satellite, suggesting a complex formation history.
The research, published in Science, used samples from Ryugu to analyze the mineral dolomite, which contains radioactive manganese that decays into chromium over time.
Universe Today also highlights Chariklo, a Centaur asteroid with a ring system, which was discovered in 2013, adding to the diversity of asteroid types.
While the publications focus on different asteroids and their unique features, they all agree that Ryugu’s early formation makes it a crucial piece in understanding the early solar system.
Despite the focus on different asteroids, the studies collectively emphasize the importance of studying these ancient bodies to unravel the mysteries of planetary formation.
According to the website, the crater, named McGetchin, is about 728 feet wide and 141 feet deep, making it the largest newly formed impact crater ever identified in the solar system.

What's still developing
- Planet building, it seems, began almost as soon as the solar system did, and some asteroids still preserve its raw ingredients.
- Most carbon-rich meteorites are studded with the remnants of molten droplets from the birth of the solar system.

- High-resolution images from ESO’s Very Large Telescope and the Large Binocular Telescope reveal that the E-type asteroid (44) Nysa may be unlike any other world in the Solar System, with three connected lobes and a newly discovered satellite that could help explain how the bizarre object formed.
- The data show that the asteroid is 80 km across and is composed of three distinct blobs, or ‘lobes,’ joined by two narrower sections that encircle the asteroid, or ‘necks’.
- The results of those observations, now published in Science Advances, have revealed for the first time that several changes have occurred in Chariklo’s rings over the last few years, revealing an unexpectedly dynamic ring system encircling the minor planet.
- While searching for exoplanets, scientists captured the first direct images of colliding objects in a neighboring star system.
- After Kalas began observing it with HST in 2004, he discovered a large belt of dusty debris at a distance of 133 astronomical units (AU) from the star, more than three times the distance from the star as the Kuiper Belt is from the sun in our solar system.
- If successful, MMX will deliver the first samples from a moon of Mars, potentially offering crucial clues about the origins of Phobos and Deimos, the evolution of Mars and the processes that shaped the early solar system.
- A fading dust cloud hints that the once-seen exoplanet Fomalhaut b was never a planet The Hubble Space Telescope spotted evidence of a collision of asteroid-sized bodies (re-created in this artist’s illustration).
- The collision provides a rare look at a young star at a time when planets have already formed and leftover asteroids are eroding away — similar to collisions that probably shaped our own solar system, astronomers report December 18 in Science.
- Through the comparison of photographs, researchers were able to prove that this was a result of a massive impact event, making it the largest new crater ever discovered in the solar system.
