Asteroid 19 Fortuna
Asteroid 19 Fortuna was discovered by English astronomer John Russell Hind on August 22, 1852. It is a large main-belt asteroid with a diameter of approximately 200 km and an irregular shape. Fortuna's name comes from the Roman goddess of luck and fortune, and it was named by John Herschel, a British astronomer and son of William Herschel who discovered Uranus. Fortuna has a relatively short rotation period of 6.25 hours, and it orbits the Sun in the main asteroid belt between Mars and Jupiter with a period of 3.9 years. It has been found to be a somewhat rare type of asteroid known as an S-type asteroid, which suggests a composition of silicate rock and metal.
Asteroid 19 Fortuna is currently in the constellation of Pisces, at a distance of 380,472,478 kilometers from Earth.

Asteroid 19 Fortuna Distance from Earth
The distance of Asteroid 19 Fortuna from Earth is currently 380,472,478 kilometers, equivalent to 2.543301 Astronomical Units. Light takes 21 minutes and 9.1196 seconds to travel from Asteroid 19 Fortuna and arrive to us.
The following chart shows the distance of Asteroid 19 Fortuna from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of 19 Fortuna from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Asteroid 19 Fortuna to Earth
Between 1 January 1900 and 31 December 2099, the closest approach of Asteroid 19 Fortuna to Earth happens on Fri Oct 15 1982 at a distance of 1.062725 Astronomical Units, or 158,981,460 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 19 Fortuna Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 19 Fortuna, according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies between the observed and predicted brightness because of their highly dynamic behaviour.
