The Sky At A Glance
January 1 marks the beginning of the International Year of Astronomy, organized to commemorate the 400th anniversary of the astronomical telescope. (See our What's New section for more.).
Earth reaches perihelion at about 10:00 AM EST on January 4, when its center is only 147,096,000 km (91,401,000 mi) from the center of the Sun. (Earth's seasons are caused by the planet's tilt on its axis, not by its distance from the Sun; currently the Northern Hemisphere is tilted away from the Sun, and is therefore experiencing winter.)
There is an annular solar eclipse on January 26, visible over the Indian Ocean and parts of Indonesia.
