An ancient object that hasn't visited the inner solar system in 50,000 years has gained the attention of stargazers across the Northern Hemisphere, and it could end up being one of the biggest ...
A green comet is flying past Earth for the first time in 50,000 years, offering skygazers a one-off opportunity to witness the celestial spectacle before it disappears from our Solar System forever.
It features a filtering system for the catalog to only display objects with matching name or ID. The pass predictions generates, among other things, the time window, minimum elevation and the apparent brightness of the object in the sky. Satellite Tracking provides detailed real-time and pass predictions for Earth orbiting satellites.
Jupiter: Look high overhead in the evening and you’ll find the largest planet in our solar system. Saturn: For the first hour after sunset, it’s visible low in the west. Show comments
Orbit of the Solar System: 17,200 pc 5.31×10 17: The average diameter of the orbit of the Solar System relative to the Galactic Center. The Sun's orbital radius is roughly 8,600 parsecs, or slightly over halfway to the galactic edge. One orbital period of the Solar System lasts between 225 and 250 million years.

Comet Hale–Bopp is expected to return to the inner Solar System. It last dominated the skies of Earth in 1996–97. 4557 November 10 Venus occults Regulus. 4747 August 14 Venus occults Regulus. c. 4785 The Great Comet of 1811 (with a 1.38 year observation arc) may return. 4903 June 29 At 08:55:01 UTC a long (7 min 0 s) total solar eclipse.
Tonight, the aurora borealis could shine across the northern half of the United States thanks to an incoming solar storm. Here's how you can watch. Aurora borealis forecast tonight through Friday.
Ignoring the influence of other Solar System bodies, Earth's orbit, also called Earth's revolution, is an ellipse with the Earth–Sun barycenter as one focus with a current eccentricity of 0.0167. Since this value is close to zero, the center of the orbit is relatively close to the center of the Sun (relative to the size of the orbit).
