Astronomers have made a groundbreaking discovery, uncovering an asteroid with a saucer-like shape that defies initial predictions and sheds new light on its origins and potential risks to Earth.
A recent study has provided new insights into the shape and origin of asteroid 2024 YR4, a space rock that was once considered a potential threat to our planet. Using advanced telescopes, scientists have imaged the asteroid in multiple wavelengths, revealing its unusual saucer-like appearance and characteristics.
Asteroid 2024 YR4 is a small celestial body that was discovered in 2024 by astronomers using advanced telescopic equipment.
The asteroid's size and composition are still unknown, but initial observations suggest it may be a stony or metallic object.
Its orbital path indicates that it passes close to 'Earth', raising concerns about potential asteroid impacts.
Scientists are currently monitoring the asteroid's movements to gather more data and predict its future trajectory.
Contrary to initial predictions, 2024 YR4 is not shaped like a flying saucer or a hockey puck, but rather a flat, spinning disk. The preferred analogy was likely due to the asteroid’s size, which was initially estimated to be around 300 feet long. However, recent research using the ‘James Webb Space Telescope’s infrared capabilities’ determined that it was actually much smaller, approximately 220 feet in diameter.
Asteroids are primarily classified into three main shapes based on their size, composition, and orbital patterns.
The most common shape is the irregular shape, accounting for about 80% of all asteroids.
These irregularly shaped asteroids have a non-uniform surface, often with craters, ridges, and valleys.
Spherical asteroids make up around 10%, while cigar-shaped or elongated asteroids account for the remaining 10%.
The shapes of asteroids are influenced by their composition, spin rate, and interactions with other celestial bodies.

The study also shed light on the asteroid’s origins. Initially, scientists suspected that 2024 YR4 came from the inner main belt, based on its composition. However, further observations revealed that it is actually an S-type asteroid rich in silicates, which originated from the central main asteroid belt. This unexpected finding suggests that the asteroid was nudged our way by ‘Jupiter‘ out of the solar system’s main asteroid belt.
Asteroids are thought to have formed during the early stages of our solar system's development, around 4.6 billion years ago.
They are remnants from the protoplanetary disk that surrounded the Sun after its formation.
Composed primarily of rock and metal, asteroids range in size from a few meters to hundreds of kilometers in diameter.
Studies suggest that many asteroids may be the result of planetary collisions or the breakdown of larger bodies over time.
While 2024 YR4 no longer poses a threat to Earth, there is still a small chance (3.8 percent) that it could veer into the Moon, potentially causing a nasty scar on its surface. However, this impact would not alter the lunar world’s orbit.
The study provides valuable insights into the characteristics of 2024 YR4 and sheds light on the asteroid belt’s complexities. Further research is needed to better understand the origins and behavior of asteroids like 2024 YR4, which can help us prepare for potential threats from space.
