New Delhi: A celestial event awaits star
gazers tomorrow night with one of the ancient asteroids
featuring a cameo in the sky.

On September 21, Juno, one of the first discovered
asteroids and the parent of many meteorite showers on the
Earth, will enjoy a cameo in the night sky theatre, and then
it`ll be at opposition, Space Popularization Association of
Communicators and Educators (SPACE) Director C B Devgun said.

"Opposition of a heavenly body is a term used in
positional astronomy to indicate when one celestial object is
on the opposite side of the sky from the sun when viewed from
the Earth," Devgun told.

Juno`s silvery glint near the planet Uranus will be
visible with a pair of binoculars, he added.

The tenth largest asteroid measures about 234 kilometers
in diameter or about one-fifteenth the diameter of the Moon.

The asteroid, which orbits the Sun on a track between
Mars and Jupiter, will be at its brightest on September 21,
when it is zooming around the Sun at about 22 kilometers per
second (49,000 miles per hour), he said.

The extra brightness will come from its position in a
direct line with the Sun and its proximity to Earth, he added.

The celestial phenomenon will be brightest at 13:04,
Devgun said.
