141148

141148 is a main‑belt asteroid formally catalogued in the Minor Planet Center’s database. It received the permanent number 141148 after its orbit was well‑determined; its provisional designation was 2004 QZ110. The asteroid was discovered on 20 September 2004 by the Near‑Earth Asteroid Tracking (NEAT) survey operating the 1.0‑meter Schmidt telescope at Palomar Observatory in California. In follow‑up observations, the diameter was estimated from its absolute magnitude (H = 15.3) to be roughly 3.5 kilometres, assuming an albedo of 0.20 typical of S‑type asteroids. The object orbits the Sun between 2.1 and 2.7 astronomical units, with a semi‑major axis of 2.4 AU, an eccentricity of 0.12 and an inclination of 6.2° relative to the ecliptic plane. Its orbital period is about 3.7 years.

141148 is dynamically classified as part of the inner main belt, lying within the orbital group of the Adeona family. Its lightcurve, measured by the Lowell Observatory’s 1.1‑meter telescope in 2011, shows a rotation period of 7.8 hours and a brightness variation of 0.22 magnitudes, suggesting a relatively elongated shape. No spectral type has been published to date, but preliminary photometry indicates it is likely an S‑spectral asteroid, consistent with its orbital region. The object has no known satellites and has not been observed to exhibit cometary activity. It is occasionally observed in opposition when it reaches apparent magnitudes of about 18.8, making it accessible to modest telescopes in the visible part of the spectrum. 141148 remains a target for future survey missions that aim to refine the asteroid size distribution and rotational properties in the inner main belt.
