1847 Stobbe
asteroid
1847 Stobbe, provisional designation A916 CA, is an asteroid from the middle region of the asteroid belt, approximately 23 kilometers in diameter.
It was discovered on 1 February 1916, by Danish astronomer Holger Thiele at Bergedorf Observatory in Hamburg, Germany. The asteroid was later named for German astronomer Joachim Stobbe.
Orbit and classification
Stobbe orbits the Sun in the central main-belt at a distance of 2.6–2.7 AU once every 4 years and 3 months (1,540 days). Its orbit has an eccentricity of 0.02 and an inclination of 11° with respect to the ecliptic. The body's observation arc begins with its official discovery observation at Bergedorf. Its first (unused) identification as A902 YB was made at Heidelberg Observatory in 1902.
Physical characteristics
On the SMASS taxonomic scheme, the X-type asteroid is characterized as a Xc-subtype, a group of bodies with intermediary spectra between those typically seen for metallic and carbonaceous bodies.
Rotation period
In March 2009, a rotational lightcurve of Stobbe was obtained from photometric observations made by French amateur astronomer Pierre Antonini at his Observatoire de Bédoin rendered a well-defined period of 5.617±0.002 hours with a brightness variation of 0.35 in magnitude (U=3), superseding a previous observation at the Roach Motel Observatory (856) in Riverside, California, that gave a period of 6.37±0.02 hours and an amplitude of 0.27 in magnitude (U=2).
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid has an albedo of 0.11–0.14 with a corresponding diameter between 22.7 and 23.9 kilometers.

Why this record matters
“1847 Stobbe” is worth following because a concise public description often conceals a longer documentary argument. Here, Stobbe and asteroid provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 5, 2026. The linked authority identifier is Q144673. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1847, 1916, 1902 and 2009.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
