Executive summary

Earth still has one true natural moon — the familiar 2,159-mile-wide satellite about 239,000 miles away — but astronomers have identified small bodies that temporarily or co-orbit with Earth, most recently asteroid 2025 PN7, described as a “quasi‑moon” that may shadow Earth until about 2083 [1] [2]. Reporting across outlets emphasizes that these objects are not gravitationally bound like the Moon and have negligible effect on Earth [3] [2].

1. What people mean by “a second moon” — headline vs. science

When headlines say “Earth has two moons” they are usually compressing a technical distinction: 2025 PN7 and objects like it are co-orbital asteroids or “quasi‑moons” that follow a Sun-centered path almost in step with Earth, not true satellites that orbit Earth directly — multiple outlets explicitly make that distinction [4] [3].

2. How astronomers classify quasi‑moons and mini‑moons

Astronomers separate permanently bound natural satellites (true moons) from temporary co‑orbitals. Quasi‑moons travel around the Sun on Earth‑like orbits and can appear to loop near Earth for years or decades; mini‑moons may be briefly captured into actual Earth orbit for months before escaping. Coverage of 2025 PN7 calls it a quasi‑moon rather than a second, bona fide moon [5] [4].

3. What we know about 2025 PN7 specifically

2025 PN7 was discovered by Pan‑STARRS and reported to the Minor Planet Center; scientists estimate it to be small (roughly the size of a building or tens of meters) and say it has likely been co‑moving with Earth for decades and could remain in that configuration until about 2083 if current orbital calculations hold [1] [6] [2].

4. Why 2025 PN7 isn’t a threat and won’t change the night sky

Experts stress 2025 PN7’s tiny size and distance mean it will have virtually no gravitational influence on Earth and will be extremely hard or impossible to see with the naked eye; its presence doesn’t make Earth look like a multi‑moon world in practice [2] [7] [6].

5. The longer history: Earth often gets temporary companions

Scientists note Earth regularly picks up transient co‑orbitals and mini‑moons. Since the 1990s, surveys have identified many asteroids in Earth‑like orbits and brief temporary captures (e.g., 2024 PT5) — so PN7 joins a known, ongoing parade of small companions rather than representing a permanent new moon [4] [3] [2].

6. Contested or overstated claims in media

Some stories and headlines (e.g., “Earth now has two moons … NASA confirms”) amplify the novelty and can mislead readers by equating quasi‑moons with the Moon itself. Several outlets explicitly counter the viral framing and emphasize that Earth still has only one true natural satellite [8] [7] [1].

7. Why this matters — science, public perception, and agendas

The discovery is scientifically interesting because co‑orbitals inform models of near‑Earth object populations and dynamical evolution; sensational headlines draw clicks and can create confusion among the public, giving some outlets an incentive to hype “two moons” language [5] [1]. Major science outlets and NASA commentary aim to correct that misunderstanding by clarifying terminology [4] [6].

8. How to verify future claims yourself

Trust reporting that cites discoverers (Pan‑STARRS, Minor Planet Center) or NASA and that distinguishes “quasi‑moon/mini‑moon” from “natural satellite.” If an item lacks those details or uses emotive phrasing (“two moons!”) without orbital context, current reporting suggests skepticism is warranted [1] [3].

Limitations and closing note: available sources consistently treat 2025 PN7 as a quasi‑moon and not a true second Moon; they do not claim PN7 will ever become a permanent, fully bound natural satellite of Earth [1] [2]. If you want primary orbital data or peer‑reviewed dynamical studies, the sources cite the Minor Planet Center and astronomical society reports as the places to look next [1] [3].
