2025 SC79 belongs to the Atira group, the newest member with an orbit inside Earth's.
2025 SC79 has a 128-day orbital period, third-shortest after 2021 PH27 and two others with 115-day periods.
Asteroids like 2025 SC79 are among the most dangerous due to detection difficulty, posing risks to near-Earth communities.
