Asteroid 1566 Icarus
Asteroid 1566 Icarus is a near-Earth asteroid discovered on June 27, 1949, by Walter Baade, an astronomer at the Palomar Observatory in California. The asteroid is named after the mythological figure Icarus, who flew too close to the sun and fell into the sea. With a diameter of approximately 1.4 kilometers, Icarus is one of the largest and best-studied near-Earth asteroids. It has a highly eccentric orbit, with a closest approach to the Sun of just 0.19 astronomical units (AU) and a farthest distance of 1.97 AU. Icarus is also notable for its frequent close approaches to Earth, with the asteroid passing within 0.042 AU (6.3 million kilometers) of our planet in 1968 and again in 2015.
The current Right Ascension of Asteroid 1566 Icarus is 19h 35m 18s and the Declination is -32° 43’ 20” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom ). The current magnitude of Asteroid 1566 Icarus is 20.71 (JPL).
- 1566 Icarus is below the horizon from Greenwich, United Kingdom .
- Given its current magnitude, 1566 Icarus is visible only through long exposure photography.

Asteroid 1566 Icarus Distance from Earth
The distance of Asteroid 1566 Icarus from Earth is currently 374,110,945 kilometers, equivalent to 2.500777 Astronomical Units. Light takes 20 minutes and 47.8998 seconds to travel from Asteroid 1566 Icarus and arrive to us.
The following chart shows the distance of Asteroid 1566 Icarus 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 1566 Icarus from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Asteroid 1566 Icarus to Earth
Between 1 January 1900 and 31 December 2099, the closest approach of Asteroid 1566 Icarus to Earth happens on Sat Jun 15 1968 at a distance of 0.042551 Astronomical Units, or 6,365,561 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 1566 Icarus Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 1566 Icarus, 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.
