The closest encounter to the Sun so far predicted is the low-mass orange dwarf star Gliese 710 / HIP 89825 with roughly 60% the mass of the Sun. [4] It is currently predicted to pass 0.1696 ± 0.0065 ly (10 635 ± 500 au) from the Sun in 1.290 ± 0.04 million years from the present, close enough to significantly disturb the Solar System's Oort ...
Their orbit is moderately eccentric, as it has an eccentricity of almost 0.52; [5] their closest approach or periastron is 11.2 AU (1.68 × 10 ^ 9 km), or about the distance between the Sun and Saturn; and their furthest separation or apastron is 35.6 AU (5.33 × 10 ^ 9 km), about the distance between the Sun and Pluto.

The stars with the most confirmed planets are the Sun (the Solar System's star) and Kepler-90, with 8 confirmed planets each, followed by TRAPPIST-1 with 7 planets. The 1,033 multiplanetary systems are listed below according to the star's distance from Earth. Proxima Centauri, the closest star to the Solar System, has three planets (b, c and d).
The closest exoplanets are those found orbiting the star closest to the Solar System, which is Proxima Centauri 4.25 light-years away. The first confirmed exoplanet discovered in the Proxima Centauri system was Proxima Centauri b, in 2016. HD 219134 (21.6 ly) has six exoplanets, the highest number discovered for any star within this range.
Major U.S. cities on the total eclipse path of totality like Cleveland and San Antonio are sure to draw huge crowds on April 8 eager to bear witness to the rare celestial event.
The first star to have its distance to Earth measured after the Sun. Also the 15th nearest stellar system to our solar system. B K7V [60] 0.595 ± 0.008 [61] 0.63 [62] 6.05 [65] 8.228 [64] Epsilon Indi A 11.867: K5V [25] 0.711 ± 0.005 [66] 0.754 ± 0.038 [23] 4.674 [67] 6.89 [68] Also the 19th nearest star system to our Solar System.
One particularly distant body is 90377 Sedna, which was discovered in November 2003.It has an extremely eccentric orbit that takes it to an aphelion of 937 AU. [2] It takes over 10,000 years to orbit, and during the next 50 years it will slowly move closer to the Sun as it comes to perihelion at a distance of 76 AU from the Sun. [3] Sedna is the largest known sednoid, a class of objects that ...
A 16-year-old girl was rescued from a hole in the sand that partially collapsed in San Diego on July 16, authorities said. Lifeguards responded to reports that the girl was buried about six to ...
