 ranked as the number @-@ two prospect in the nation at the time , announced his verbal commitment to Michigan . Within hours of the commitment , ESPN said that Michigan 's ranked as the fifth @-@ best class in the nation . All three signed a National Letter of Intent with the team on November 9 . After several other schools announced their commitments , the McGary 's commitment moved Michigan from outside the top 25 to the seventh @-@ best class in the nation , according to ESPN . Michael " Spike " Albrecht committed to Michigan on April 6 , 2012 .   = = Team Players Drafted into the NBA = =   = Upsilon Andromedae b =   Upsilon Andromedae b ( abbreviated υ Andromedae b , υ And b ) , occasionally designated Upsilon Andromedae Ab ( to distinguish it from the red dwarf Upsilon Andromedae B ) , also named Saffar , is an extrasolar planet approximately 44 light @-@ years away from the Sun in the constellation of Andromeda . The planet orbits the Solar twin star , Upsilon Andromedae A , approximately every five days . Discovered in June 1996 by Geoffrey Marcy and R. Paul Butler , it was one of the first hot Jupiters to be discovered . It is also one of the first non @-@ resolved planets to be detected directly . Upsilon Andromedae b is the innermost known planet in its planetary system .   In July 2014 the International Astronomical Union launched a process for giving proper names to certain exoplanets and their host stars . The process involved public nomination and voting for the new names . In December 2015 , the IAU announced the winning name was Saffar for this planet . The winning name was submitted by the Vega Astronomy Club of Morocco and honours the 11th Century astronomer Ibn al @-@ Saffar of Muslim Spain .   = = Discovery = =   Like the majority of known extrasolar planets , Upsilon Andromedae b was detected by the variations in its star 's radial velocity caused by the planet 's gravity . The variations were detected by making sensitive measurements of the Doppler shift of Upsilon Andromedae 's spectrum . The planet 's existence was announced in January 1997 , together with 55 Cancri b and the planet orbiting Tau Boötis .   Like 51 Pegasi b , the first extrasolar planet discovered around a normal star , Upsilon Andromedae b orbits very close to its star , closer than Mercury does to our Sun . The planet takes 4 @.@ 617 days to complete an orbit , with a semimajor axis of 0 @.@ 0595 AU .   A limitation of the radial velocity method used to detect Upsilon Andromedae b is that only a lower limit on the mass can be found . In the case of Upsilon Andromedae b , this lower limit is 68 @.@ 7 % of the mass of Jupiter , though depending on the inclination of the orbit , the true mass may be much greater . However , astronomers found recently that inclination of the orbital plane is around 25 ° and the true mass may be about 1 @.@ 4 MJ . Coplanarity is not to be assumed ; the mutual inclination between c and d is 35 degrees .   = = Physical characteristics = =   Given the planet 's high mass , it is likely that Upsilon Andromedae b is a gas giant with no solid surface .   The Spitzer Space Telescope measured the planet temperature , and found that the difference between the two sides of Upsilon Andromedae b of about 1 @,@ 400 degrees Celsius , ranging from minus 20 to 230 degrees to about 1 @,@ 400 to 1 @,@ 650 degrees Celsius . The temperature difference has led to speculation that Upsilon Andromedae b is tidal locked with the same side always facing Upsilon Andromedae A.   Sudarsky had , on the assumption that the planet is similar to Jupiter in composition and that its environment is close to chemical equilibrium , predicted Upsilon Andromedae b to have reflective clouds of silicates and iron in its upper atmosphere . The cloud deck instead absorbs the sun 's radiation ; between that and the hot , high pressure gas surrounding the mantle , exists a stratosphere of cooler gas . The outer shell of dark , opaque , hot cloud is assumed to consist of vanadium and titanium oxides ( " pM planets " ) , but other compounds like tholins cannot be ruled out yet .   The planet is unlikely to have large moons , since tidal forces would either eject them from orbit or destroy them on short timescales compared to the age of the system .   The planet ( with 51 Pegasi b ) was deemed a candidate for direct imaging by Planetpol . Preliminary results from polarimetric studies indicate that the planet has predominately blue color
