1263 varsavia, provisional designation 1933 ff, is an asteroid from the central region of the asteroid belt, approximately 40 kilometers in diameter. it was discovered on 23 march 1933, by belgian astronomer sylvain arend at uccle observatory in belgium. it is named for the city of warsaw. | wikipedia |
this minor planet was named by tadeusz banachiewicz after the latin name of the city of warsaw, capital of poland. the naming citation includes a note of thanks for the support given by the city's observatory. naming citation was first published in german by astronomisches rechen-institut (ri 843). | wikipedia |
on july 18, 2003, a stellar occultation by 1263 varsavia was observed at multiple sites. the measured chords yielded an equivalent diameter of 41 ± 8 km. the profile best matched a spin vector of (λ, β) = (341°, −14°) in elliptical coordinates. | wikipedia |

the 1952–53 season was the fifty-first season in which dundee competed at a scottish national level, playing in division a, where the club would finish in 7th place. dundee would also compete in both the scottish cup and the scottish league cup. dundee would become the first scottish team to win the league cup in consecutive seasons, with a late bobby flavell double giving them a 2–0 win over kilmarnock and winning them their third major honour. they would not see this success replicated in the scottish cup, losing at home against rangers. the attendance for this game, 43,024, is an all-time attendance record at dens park. at the beginning of the season, dundee would try out a unique navy-and-white quartered home kit per the request of manager george anderson, but proved highly unpopular with both players and fans. when anderson took ill in september 1952 and his assistant reg smith took over coaching duties temporarily, the team agreed to switch back to their traditional navy shirt, with the addition of navy stripes on the shorts and red socks. | wikipedia |

1927 suvanto, provisional designation 1936 fp, is a stony eunomian asteroid from the central region of the asteroid belt, approximately 12 kilometers in diameter. it was discovered on 18 march 1936, by finnish astronomer rafael suvanto at the turku observatory in southwest finland. the asteroid was posthumously named in honor of the discoverer. | wikipedia |
this minor planet was named in memory of rafael suvanto (credited discoverer), assistant of yrjö väisälä. suvanto died during the last days of the finnish winter war of in the battle of summa (also see naming of asteroid 1928 summa). the approved naming citation was published by the minor planet center on 1 august 1980 (m.p.c. 5450). | wikipedia |
suvanto is a member of the eunomia family, the most prominent family in the intermediate main-belt, which mostly consists of stony s-type asteroids. it orbits the sun at a distance of 2.3–3.0 au once every 4 years and 4 months (1,577 days). its orbit has an eccentricity of 0.15 and an inclination of 13 ° with respect to the ecliptic. | wikipedia |

1508 kemi, provisional designation 1938 up, is an eccentric, carbonaceous asteroid and one of the largest mars-crossers, approximately 17 kilometers in diameter. discovered by heikki alikoski at turku observatory in 1938, the asteroid was later named after the finnish town of kemi and the kemi river. | wikipedia |
this minor planet was named after the finnish town of kemi and the kemi river (kemijoki), the largest river in finland, on which the town lies. the naming agrees with the established pattern of giving high-inclination asteroids four-letter names. the official naming citation was published by the minor planet center on 20 february 1976 (m.p.c. 3928). | wikipedia |
according to the surveys carried out by the japanese akari satellite and the neowise mission of nasa's wide-field infrared survey explorer, kemi measures between 15.78 and 17.98 kilometers in diameter and its surface has an albedo between 0.084 and 0.11. the collaborative asteroid lightcurve link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 21.86 kilometers based on an absolute magnitude of 12.03. | wikipedia |
in 2016, an international study modeled a lightcurve with a concurring period of 9.19182 hours. it also determined two spin axis at (352.0°, 72.0°) and (166.0°, 73.0°) in ecliptic coordinates (λ, β). | wikipedia |
several rotational lightcurves of kemi have been obtained from photometric observations since the 1990s. analysis of the lightcurves gave a consolidated rotation period of 9.196 hours with a brightness variation between of 0.25 and 0.55 magnitude (u=2/3/3/2). | wikipedia |
in the smass classification, kemi is a common carbonaceous c-type asteroid. in the tholen classification, the body's spectral type is ambiguous (bcf), closest to that of a bright carbonaceous b-type and somewhat similar to a c- and f-type asteroid. | wikipedia |
it orbits the sun at a distance of 1.6–3.9 au once every 4 years and 7 months (1,685 days). its orbit has an eccentricity of 0.42 and an inclination of 29 ° with respect to the ecliptic. the body's observation arc begins at uccle in may 1935, more than 3 years prior to its official discovery observation at turku. | wikipedia |
kemi is a mars-crossing asteroid as it crosses the orbit of mars at 1.666 au. because of its high inclination, it has been grouped with the pallas family (801), an asteroid family of bright carbonaceous asteroids, as well as with the "phaethon group", despite its untypical spectrum. | wikipedia |
