1066 Lobelia, provisional designation {{mp|1926 RA}}, is a bright background asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 1 September 1926, by astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in Germany. The asteroid was named after the flowering plant Lobelia (lobelias).

Orbit and classification

Lobelia is a non-family asteroid from the main belt's background population. It orbits the Sun in the inner main-belt at a distance of 1.9–2.9 AU once every 3 years and 9 months (1,360 days; semi-major axis of 2.40 AU). Its orbit has an eccentricity of 0.21 and an inclination of 5° with respect to the ecliptic.

The asteroid was first observed at Heidelberg as {{mp|A911 QB}} in August 1911. The body's observation arc begins at Simeiz Observatory in October 1926, one month after its official discovery observation at Heidelberg.

Physical characteristics

The asteroid's spectral type is unknown.

= Rotation period =

As of 2017, no rotational lightcurve of Lobelia was obtained from photometric observations. The body's rotation period, spin axis and shape remain unknown.

= Diameter and albedo =

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Lobelia measures 6.014 kilometers in diameter and its surface has a high albedo of 0.488.

Naming

This minor planet was named after the Indian tobacco flower, Lobelia, a genus of flowering plants also known as lobelias. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 ({{small|H 101}}).

= Reinmuth's flowers =

Due to his many discoveries, Karl Reinmuth submitted a large list of 66 newly named asteroids in the early 1930s. The list covered his discoveries with numbers between {{MoMP|1009|(1009)}} and {{MoMP|1200|(1200)}}. This list also contained a sequence of 28 asteroids, starting with 1054 Forsytia, that were all named after plants, in particular flowering plants (also see list of minor planets named after animals and plants).
