He says the object was protoplanet-sized, or about 150 miles (250 km) in diameter, two times larger and 10 times more massive than previous estimates.Deborah Byrd created the EarthSky radio series in 1991 and founded EarthSky.org in 1994. Those estimates – for Combining these new estimates with the fact that there are even larger impact basins on the moon and other planets, Schultz concludes that protoplanet-sized asteroids may have been common in the early solar system. The LROC NAC image shows that a small wrinkle ridge, which is several hundred meters long, passes close to the CE-3 landing site (Xiao et al., 2014; Wu et al., 2016, Wu et al., 2018).

A science communicator and educator since 1976, Byrd believes in science as a force for good in the world and a vital tool for the 21st century. Today, she serves as Editor-in-Chief of this website. Autolycus is a lunar impact crater that is located in the southeast part of Mare Imbrium.The crater is named after the ancient Greek astronomer Autolycus of Pitane.
This beautiful image – via Imbrium Basin measures about 750 miles (1,200 km) across. Schultz used With these experiments, Schultz was able to show that those grooves were likely formed by chunks of the impactor that sheared off on initial contact with the surface.
He said:The large basins we see on the moon and elsewhere are the record of lost giants.Astronomers point to the asteroid Vesta as an example of Bottom line: Peter Schultz at Brown University has a new estimate for the size of the object that struck the moon to create Mare Imbrium, the Sea of Showers or Sea of Rains.
Schaber traced the source of the flows to a region of Mare Imbrium directly north of Euler Crater, and our flow boundary mapping finds good agreement with this. Many young wrinkle ridges were found inside Mare Imbrium using Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) high-resolution images. The young ridges were mapped, and they have a winding and arched morphology.
The young ridges were mainly distributed in the inner region of Imbrium basin, which may suggest that the thermal and structural evolution of the inside area of Imbrium basin was protracted.We use cookies to help provide and enhance our service and tailor content and ads.

A thorough investigation of young wrinkle ridges was then performed in Mare Imbrium, and Fig. She has won a galaxy of awards from the broadcasting and science communities, including having an asteroid named 3505 Byrd in her honor. Imbrium Basin measures about 750 miles (1,200 km) across. Several tiny craters north of Diophantus have been assigned names by the IAU. Plato crater is also prominent by association; the crater is located just north of 1145-kilometer-wide Mare Imbrium. Determining their formation times and morphology is important in understanding the Moon's late evolution. He also said that his new findings, which are published in the journal And he said his work suggests that – given the sizes of other impact basins in the moon, Mars and Mercury – the early solar system must have been well stocked with protoplanet-sized objects, which he calls “the lost giants.”Mare Imbrium on the moon.
This cleft follows a generally east–west path across the Mare Imbrium.
Many young wrinkle ridges were found inside Mare Imbrium.The youngest ridges were estimated to be as young as 10 Ma.Young ridges are concentrated in the inner region of the Imbrium basin.Wrinkle ridges are common landforms widely distributed in the lunar maria.
