26858 Misterrogers /ˌmɪstər ˈrɒdʒərz/ is a Mars crossing asteroid named after children's television host Fred Rogers.^[6] Rogers, who had a lifelong fascination with the sky and astronomy—he obtained a pilot's license while still in high school^{[citation needed]}—also produced with the Carnegie Science Center in Pittsburgh a planetarium show called The Sky above Mister Rogers' Neighborhood, which is still shown at many planetariums across the United States.^{[citation needed]}

The International Astronomical Union citation reads as follows:

Fred McFeely Rogers (1928–2003) was a tireless and passionate advocate for children who taught that everyone is unique and deserving of love and respect 'just the way you are'. For more than 30 years he used his public television program Mister Rogers' Neighborhood as a vehicle of service to the youngest members of the human family.

The naming was proposed, and citation prepared, by John G. Radzilowicz, Director of the Henry Buhl, Jr. Planetarium & Observatory at the Carnegie Science Center.^[7]
