The asteroid was named for the city of Portland, Maine, where Hastings was a church minister at the time. In November 2015, amateur astronomers captured it with images of comet 67P/Churyumov–Gerasimenko. Portlandia came to opposition in March 2016 at apparent magnitude 13.2. This body is orbiting at a distance of  with a period of  and an eccentricity of 0.109. The orbital plane is inclined at an angle of 8.2° to the plane of the ecliptic. 757 Portlandia is classified as an X-type asteroid and is a core member of the proposed Athor asteroid family, named after 161 Athor. This asteroid spans a girth of  and is rotating with a period of 6.58 hours. During 2003, the asteroid was observed occulting a star. The resulting chords were used to determine a diameter estimate of 36.7 km. References
