2213 Meeus,provisional designation1935 SO1,is a bright backgroundasteroidfrom the inner regions of theasteroid belt,approximately 5 kilometers (3 miles) in diameter. It was discovered on 24 September 1935, by Belgian astronomerEugène Delporteat theRoyal Observatory of Belgiumin Uccle.[1]The presumedS-type asteroidhas a shortrotation periodof 2.65 hours.[4]It was named for Belgian amateur astronomer and meteorologistJean Meeus.[1]

Orbit and classification
editMeeusis a non-familyasteroid of the main belt'sbackground populationwhen applying thehierarchical clustering methodto itsproper orbital elements.[3]Based on osculating Keplerianorbital elements,the asteroid has also been classified as a member of theFlora family(402), a giantasteroid familyand the largest family of stony asteroids in the main-belt.[4]
It orbits the Sun in theinnermain-belt at a distance of 1.7–2.7AUonce every 3 years and 3 months (1,190 days;semi-major axisof 2.2 AU). Its orbit has aneccentricityof 0.23 and aninclinationof 5°with respect to theecliptic.[2]The body'sobservation arcbegins with its official discovery observation at Uccle in 1935.[1]
Physical characteristics
editMeeusis an assumed stonyS-type asteroid.[4]
Rotation period
editIn August 2013, a rotationallightcurveofMeeuswas obtained fromphotometricobservations by Italian astronomers of the Tuscolana Association of Astronomy (D06). Lightcurve analysis gave arotation periodof 2.651 hours with a brightness amplitude of 0.19magnitude(U=3-).[4][8]
Diameter and albedo
editAccording to the survey carried out by theNEOWISEmission of NASA'sWide-field Infrared Survey Explorer,Meeusmeasures between 4.59 and 5.194 kilometers in diameter and its surface has a highalbedobetween 0.3467 and 0.439.[5][6][7]
TheCollaborative Asteroid Lightcurve Linkassumes an albedo of 0.24 – derived from8 Flora,theparent bodyof the Flora family – and calculates a diameter of 5.67 kilometers based on anabsolute magnitudeof 13.4.[4]
Naming
editThisminor planetwas named after Belgian amateur astronomer and professional meteorologistJean Meeus(born 1928), who, in 1986, received theAmateur Achievement Award of the Astronomical Society of the Pacific.[1]The official naming was proposed by Eric S. Fogelin(see2181),Jay U. GunterandEdward Bowell,and published by theMinor Planet Centeron 1 August 1981 (M.P.C.6208).[10]
