Alpha Centauri A and B are a closely tied pair of Sun-like stars, whereas the closest star to the Sun, the small red dwarf Proxima Centauri, orbits the pair at a distance of 0.2 light-years. In 2016, a potentially habitable exoplanet was found to be orbiting Proxima Centauri, called Proxima Centauri b, the closest confirmed exoplanet to the Sun ...
A photo shared by users across social media claiming to show the closest image of the sun's surface is heavily edited and was not captured by NASA.
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 ...
The images, obtained in March 2023 by the ESA's Solar Orbiter, represent what the agency says are the highest-resolution views of the sun's surface, known as the photosphere, to date.
In June 2020, Solar Orbiter came within 77,000,000 km (48,000,000 mi) of the Sun, and captured the closest pictures of the Sun ever taken. [27] Mission timeline
It has already swept past the Sun 21 times, getting ever nearer, but the Christmas Eve visit is record-breaking. At its closest approach, the probe is 3.8 million miles (6.2 million km) from our ...
A body's closest approach to the Sun is called its perihelion, whereas its most distant point from the Sun is called its aphelion. [53]: 9-6 With the exception of Mercury, the orbits of the planets are nearly circular, but many comets, asteroids, and Kuiper belt objects follow highly elliptical orbits. Kepler's laws only account for the ...
The six Earth images are positions along the orbital ellipse, which are sequentially the perihelion (periapsis—nearest point to the Sun) on anywhere from January 2 to January 5, the point of March equinox on March 19, 20, or 21, the point of June solstice on June 20, 21, or 22, the aphelion (apoapsis—the farthest point from the Sun) on ...
