Jog by Jupiter, saunter past Saturn and meander about Mercury: Get a walking tour of the solar system and let Bill Nye, the Science Guy, be your guide, on March 7 in downtown Ithaca.

Nye will be making his last visit as a Cornell University Frank H.T. Rhodes Class of 1956 Professor, March 6-11, and he has a couple of public activities planned.

On March 7, Nye will lead a public tour of Ithaca's famous downtown Carl Sagan Planet Walk, a scale model of the solar system built in the center of the city of Ithaca. It was dedicated in 1997. Those who want to join in the walk should meet at the sun station marker in front of Center Ithaca on the Ithaca Commons at 3 p.m. The walk is hosted by the Ithaca Sciencenter and Cornell. It will conclude at the Sciencenter, 602 First St., where warm refreshments will be provided.

In addition to walking the walk, Nye will be talking the talk at a public lecture, "Everyone Talks About The Weather," Wednesday, March 8, at 8 p.m. in the Statler Auditorium on campus. A limited number of free tickets can be obtained at the Willard Straight Hall box office on campus, (607) 255-3430.

Nye, who was appointed a Rhodes professor in 2001, is a 1977 graduate of Cornell's Sibley School of Mechanical and Aerospace Engineering. He is best known for his weekly half-hour, Emmy Award-winning show, "Bill Nye, The Science Guy," which aired on PBS from 1992 to 1998.
