Asteroid 18883 Domegge was discovered by Gina Fedon and Mark Abraham from their EverStaR Observatory. The name was chosen by Gina, who grew up in Domegge di Cadore, a village in the Italian Eastern Alps, the Dolomites†. She remembered the nights she spent looking up at the stars outside her childhood home, and as her interest in astronomy started there, she thought the name would be appropriate.
