Asteroid 14 Irene
Asteroid 14 Irene is a relatively large asteroid with a diameter of approximately 147 kilometers. It was discovered on May 19, 1851, by John Russell Hind, an English astronomer. The asteroid was named after the Greek goddess of peace, Irene, who was one of the Horae, the goddesses of the seasons and the natural order. Irene orbits the Sun in the main asteroid belt between Mars and Jupiter, with a semi-major axis of approximately 2.65 astronomical units (AU) and an orbital period of about 4.31 years. The asteroid is classified as a C-type asteroid, indicating that its surface is likely composed of carbonaceous materials. Astronomers have detected a small moon orbiting Irene, which has a diameter of about 4.4 kilometers and orbits at a distance of approximately 800 kilometers from the asteroid's center.
Asteroid 14 Irene is currently in the constellation of Cetus.
The current Right Ascension of Asteroid 14 Irene is 00h 28m 31s and the Declination is -07° 59’ 06” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom ). The current magnitude of Asteroid 14 Irene is 11.78 (JPL).

Asteroid 14 Irene Distance from Earth
The distance of Asteroid 14 Irene from Earth is currently 365,394,582 kilometers, equivalent to 2.442512 Astronomical Units. Light takes 20 minutes and 18.8251 seconds to travel from Asteroid 14 Irene and arrive to us.
The following chart shows the distance of Asteroid 14 Irene 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 14 Irene from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Asteroid 14 Irene to Earth
Between 1 January 1900 and 31 December 2099, the closest approach of Asteroid 14 Irene to Earth happens on Fri Apr 2 2088 at a distance of 1.175276 Astronomical Units, or 175,818,790 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 14 Irene Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 14 Irene, 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.
