The Solar System remains in a relatively stable, slowly evolving state by following isolated, gravitationally bound orbits around the Sun. [28] Although the Solar System has been fairly stable for billions of years, it is technically chaotic, and may eventually be disrupted. There is a small chance that another star will pass through the Solar ...
Axis of evil: Some large features of the microwave sky at distances of over 13 billion light-years appear to be aligned with both the motion and orientation of the solar system. Is this due to systematic errors in processing, contamination of results by local effects, or an unexplained violation of the Copernican principle ?
About 1.3 million years ago the object may have passed within a distance of 0.16 parsecs (0.52 light-years) to the nearby star TYC 4742-1027-1, but its velocity is too high to have originated from that star system, and it probably just passed through the system's Oort cloud at a relative speed of about 15 km/s (34,000 mph; 54,000 km/h).
Solar phenomena are natural phenomena which occur within the atmosphere of the Sun. They take many forms, including solar wind , radio wave flux , solar flares , coronal mass ejections , [ 1 ] coronal heating and sunspots .

A conjunction of Mars and Jupiter in the morning of 1 May 2011, when, about an hour before sunrise, five of the Solar System's eight planets and the Moon could be seen from Cerro Paranal, Chile. [5] More generally, in the particular case of two planets, it means that they merely have the same right ascension (and hence the same hour angle ...
The Sun is 1.4 million kilometers (4.643 light-seconds) wide, about 109 times wider than Earth, or four times the Lunar distance, and contains 99.86% of all Solar System mass. The Sun is a G-type main-sequence star that makes up about 99.86% of the mass of the Solar System. [ 26 ]
