Mombasa–Nairobi Standard Gauge Railway Mombasa–Nairobi Standard Gauge Railway The Mombasa–Nairobi Standard Gauge Railway is a standard-gauge railway (SGR) in Kenya that connects the large Indian Ocean city of Mombasa with Nairobi, the country's capital and largest city. This SGR runs parallel to the defunct, narrow-gauge Uganda Railway that was completed in 1901 under British colonial rule.

1428 Mombasa years prior to its official discovery at Johannesburg. American astronomer Robert Stephens obtained a rotational lightcurve of "Mombasa" in June 2012. Light-curve analysis gave a rotation period of 16.67 hours with a brightness variation of 0.16 magnitude (). Previous lightcurves were obtained by French amateur astronomer René Roy in February 2006 (17.6 hours, Δ0.15 mag; ), as well as by Scot Hawkins and Richard Ditteon at Oakley Observatory in May 2007 (17.12 hours, Δ0.25 mag; ). On the SMASS taxonomic scheme, "Mombasa" is a , an intermediate between the carbonaceous C and X-type, while it is also described as a
