The Infrared Astronomical Satellite (IRAS) was the first space telescope to perform a survey of the entire night sky at infrared wavelengths. Launched on 25 January 1983, its mission lasted ten months. The telescope was a joint project of the United States (NASA), the Netherlands (NIVR), and the United Kingdom (SERC). Over 250,000 infrared sources were observed at 12, 25, 60, and 100 micrometer wavelengths.

Wide-field Infrared Survey Explorer is a NASA infrared astronomy space telescope in the Explorers Program. It was launched in December 2009, and placed in hibernation mode in February 2011, before being re-activated in 2013 and renamed the Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE). WISE discovered thousands of minor planets and numerous star clusters. Its observations also supported the discovery of the first Y-type brown dwarf and Earth trojan asteroid.

It is one of the 60 largest Jupiter trojans and was named after Phoenix (Phoinix) from Greek mythology.
2121 Sevastopol, provisional designation 1971 ME, is a stony Florian asteroid and synchronous binary system from the inner regions of the asteroid belt, approximately 10 kilometers in diameter. It was discovered on 27 June 1971, by Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnij, on the Crimean peninsula. Its minor-planet moon was discovered in 2010.

1655 Comas Solà, provisional designation 1929 WG, is a rare-type asteroid from the central region of the asteroid belt, approximately 36 kilometers in diameter. It was discovered on 28 November 1929, by Spanish astronomer of Catalan origin, Josep Comas i Solà at the Fabra Observatory in Barcelona, Spain. It was later named after the discoverer.
16560 Daitor is a large Jupiter trojan from the Trojan camp, approximately 44 kilometers in diameter. It was discovered on 2 November 1991, by Belgian astronomer Eric Elst at the La Silla site of the European Southern Observatory in Chile. The carbonaceous C-type asteroid is one of the largest Jupiter trojans with an unknown rotation period. It was named after the Trojan warrior Daitor from Greek mythology.
Martin Gerard Connors is a Canadian astronomer and professor.
