China’s Tianwen-2 spacecraft has approach within about 12.5 miles of the near-Earth quasi-moon Kamo'oalewa after a 400-day, 620-million-mile journey, enabling the first close photos and potentially a sample collection using an anchor-and-attach method, signaling a major milestone for China's space program.
China’s Tianwen-2 spacecraft is within about 12.5 miles of Kamo'oalewa, one of Earth's quasi-moons, to capture the first clear photo and potentially collect surface samples over a year-long co-orbital mission using anchor-and-attach or touch-and-go methods; success would make China the third nation to sample an asteroid, though the tiny, rapidly rotating target poses significant challenges.
This week’s science roundup highlights a Bose-Einstein condensate experiment where time emerges inside a mini-universe, NASA upgrading its ISS lab to study such quantum states, and other quantum advances including using quantum computers to create a fusion-relevant material; researchers also report a real-world attempt to thicken Arctic sea ice by flooding with seawater. Archaeology reveals one of the oldest graves of a free Black person in the U.S.—Sebastian, known as 'Boston,' who died in 1729 in Boston. In space news, China’s Tianwen-2 mission captured the first photo of Earth’s quasi-moon, hinting at future sample collection.
China's Tianwen-2 spacecraft has delivered the first close-up image of Earth's quasi-moon Kamo'oalewa (2016 HO3) after a roughly 400-day journey, suggesting a small, rubble-pile asteroid around 40–100 meters in size and signaling that planned sample collection could be more difficult than expected. If successful, any samples would be returned to Earth in 2027, making China the third country to achieve asteroid sample return; the mission will later pivot to a second target, 311P/PanSTARRS, in 2035.
China released the first image of an asteroid some astronomers say could be a fragment from the Moon, and the Tianwen-2 mission is planned to collect a sample and return it to Earth.
Kamoʻoalewa, a small near-Earth object that travels with Earth like a quasi-moon, may be a fragment of the Moon blown into space by an ancient impact. China’s Tianwen-2 has reached the object and will attempt to collect a few hundred grams of material using multiple sampling methods before returning a capsule to Inner Mongolia in 2027. A lunar origin would be confirmed if the rock’s minerals and isotopes match Moon rock; if not, the evidence would favor an asteroid origin. The mission will map and study Kamoʻoalewa through 2027, potentially providing a decisive answer about whether Earth has been shadowed by a piece of its own satellite.
China’s CNSA Tianwen-2 spacecraft has reached the near-Earth quasi-moon Kamo'oalewa and is set to attempt sampling on July 4, 2026, potentially via a touch‑and‑go grab or direct drilling, collecting about 100 grams of surface material. After mapping the rock from ~300 m to 20 km altitude, the samples would return to Earth in late 2027, with a planned 2035 follow‑up to study 311P/PanSTARRS. The mission could reveal Kamo'oalewa’s origin—perhaps lunar debris or a main-belt fragment—while showcasing China’s space capabilities and informing future asteroid resource exploration.
The article explores the ambiguity in defining what constitutes a moon, highlighting the discovery of quasi-moons and mini-moons around Earth and other planets, and discusses the ongoing debate among scientists about proper terminology and classifications in astronomy.
The article explores whether the asteroid 2025 PN7 could be a natural quasi-moon or a relic of the Soviet Zond 1 mission to Venus, analyzing its trajectory and potential technological origin, and discusses broader implications of interstellar objects and extraterrestrial visitation.
Astronomers have identified an asteroid, 2025 PN7, that will act as a quasi-moon for Earth until 2083, sharing a similar orbit but not actually orbiting the planet, and this phenomenon is part of ongoing discoveries about small objects in our solar system.
Astronomers have discovered a small quasi-moon near Earth, named 2025 PN7, which has likely been in Earth's vicinity for about 60 years. This tiny asteroid, estimated to be around 98 feet across, follows an orbit that brings it close to Earth periodically, but it remains challenging to observe due to its size and faintness. The discovery highlights the potential for more such objects and the importance of studying them to understand our solar system better.
NASA has confirmed that the object dubbed Earth's 'second moon' is actually a quasi-moon, an asteroid that orbits the sun in near-lockstep with Earth, and not a true moon. Known as 2025 PN7, it has likely been near Earth for about 60 years and will remain so until around 2083, but it has minimal gravitational impact due to its small size.
NASA has confirmed the existence of a small asteroid, 2025 PN7, which acts as a 'quasi-moon' by traveling almost in sync with Earth. Discovered by the University of Hawaii, it has been orbiting Earth for about 60 years at a distance of over 4 million kilometers, without affecting tides or gravity, and is expected to remain with us until 2083.
NASA has confirmed that Earth has a temporary quasi-moon, asteroid 2025 PN7, which has been orbiting in sync with Earth since around 1963 and will likely stay until 2083, providing valuable insights into asteroid dynamics and Earth's gravitational influence.
A quasi-moon is a small object that shares Earth's orbit around the Sun without being a true satellite, and the asteroid 2023 FW13 has been silently orbiting Earth for over 60 years, revealing new insights into these rare cosmic companions.
