cds-question@unistra.frasteroidsphotometryOn its journey to comet 67P/Churyumov-Gerasimenko, the International Rosetta Mission (ESA) was planned to fly-by two asteroids: (2867) Steins and (21) Lutetia. Although classified as an M-type asteroid because of its high albedo, its reflectance spectrum in the near and mid-infrared region, suggests a primitive composition, more typical of C-type asteroids. Results from ground-based observations are indicative of compositional variegation and of at least one significantly large crater on the surface of this asteroid. We analyse photometric and spectroscopic data of the asteroid, obtained from ground-based observations, to support the data taken by the spacecraft.2011A&A...527A..42Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/527/A42CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/521/A19 : 21 Lutetia UBVRI light curves (Lamy+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/527/A42https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/527/A42http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/527/A42https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/527/A42https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/527/A42http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/527/A42GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/527/A42/table2Julian dates, phases and relative magnitudes of the combined lightcurve presented in Figure 4 for asteroid (21) LutetiarecnoRecord number assigned by the VizieR team.
