East African springhare East African springhare The East African springhare ("Pedetes surdaster"), is not closely related to the hare, but is a member of the Pedetidae, a rodent family. "Pedetes surdaster" was recognised by Matthee and Robinson in 1997 as a species distinct from the southern African springhare "(P. capensis)" based on genetic, morphological, and ethological differences. "P. capensis" from South Africa has fewer chromosomes (2n= 38) than does "P. surdaster" which has (2n = 40) and some other genetic variations. The species was confirmed by Dieterlen in 2005. This species is found in central and southern Kenya and most of Tanzania. A
Celestial equator Celestial equator The celestial equator is the great circle of the imaginary celestial sphere on the same plane as the equator of Earth. This plane of reference bases the equatorial coordinate system. In other words, the celestial equator is an abstract projection of the terrestrial equator into outer space. Due to Earth's axial tilt, the celestial equator is currently inclined by about 23.44° with respect to the ecliptic (the plane of Earth's orbit). An observer standing on Earth's equator visualizes the celestial equator as a semicircle passing through the zenith, the point directly overhead. As the observer moves north (or
