As of 2022, the precise location of the Solar System in the clouds is an open question in astronomy. [157] Within 10 light-years of the Sun there are relatively few stars, the closest being the triple star system Alpha Centauri, which is about 4.4 light-years away and may be in the Local Bubble's G-Cloud. [158]
This revolution is known as the Solar System's galactic year. [275] The solar apex, the direction of the Sun's path through interstellar space, is near the constellation Hercules in the direction of the current location of the bright star Vega. [276] The plane of the ecliptic lies at an angle of about 60° to the galactic plane. [c]
The Sun moves through the heliosphere at 84,000 km/h (52,000 mph). At this speed, it takes around 1,400 years for the Solar System to travel a distance of 1 light-year, or 8 days to travel 1 AU (astronomical unit). [113] The Solar System is headed in the direction of the zodiacal constellation Scorpius, which follows the ecliptic. [114]
Weather permitting, Jupiter will not only be brighter than most other stars and planets in the evening sky, but will also be visible all night long. Jupiter, ascending: See our solar system’s ...
If it were at the centre of the Solar System, it would extend 90% of the way to the orbit of Mercury. [62] The radius and temperature relative to the Sun means that it is 10,700 times more luminous than the Sun, and its position in the H-R diagram relative to theoretical evolutionary tracks means that it is 8.0 ± 0.3 times as massive as the ...

Scientists say they are rethinking how the weather works after creating a 3D map of an exoplanet 900 light-years away ... this is the first study in such detail of a world outside our solar system.
Based on results from the Gaia telescope's second data release from April 2018, an estimated 694 stars will approach the Solar System to less than 5 parsecs in the next 15 million years. Of these, 26 have a good probability to come within 1.0 parsec (3.3 light-years) and another 7 within 0.5 parsecs (1.6 light-years). [3]
