402 Chloë
402 Chloë (Minor planet provisional designation, ''prov. designation'': ''or'' ) is a large Asteroid belt, main-belt asteroid. It was discovered by French astronomer Auguste Charlois on 21 March 1895 from Nice. This asteroid is orbiting the Sun at a distance of with a orbital period, period of and an orbital eccentricity, eccentricity of 0.11. The orbital plane is inclined at an angle of 11.8° to the plane of the ecliptic. This asteroid spans a girth of approximately 54 km. It is classified as a K-type asteroid and is a 234 Barbara, Barbarian. Analysis of the asteroid light curve, based on Photometry (astronomy), photometric data collected during 2009, show a rotation period of with a brightness variation of in apparent magnitude, magnitude.

Lightcurve
In astronomy, a light curve is a graph of light intensity of a celestial object or region as a function of time, typically with the magnitude of light received on the y axis and with time on the x axis. The light is usually in a particular frequency interval or band. Light curves can be periodic, as in the case of eclipsing binaries, Cepheid variables, other periodic variables, and transiting extrasolar planets, or aperiodic, like the light curve of a nova, a cataclysmic variable star, a supernova or a microlensing event or binary as observed during occultation events. The study of the light curve, together with other observations, can yield considerable information about the physical process that produces it or constrain the physical theories about it. Variable stars Graphs of the apparent magnitude of a variable star over time are commonly used to visualise and analyse their behaviour. Although the categorisation of variable star types is increasingly done from their spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
