18. Dez. 2017 · However, near-Sun comets reach perihelion closer to the Sun than this, experiencing extreme solar wind and insolation conditions, where they undergo thermal desorption (e.g., Martín-Doménech et al. 2014), sublimation, radiation spallation, and other processes. Those comets that approach nearest to our star also experience strong gravitational tides. The latter, along with heat-induced ...
Our Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It’s about 93 million miles (150 million kilometers) from Earth and it’s our solar system’s only star. Without the Sun’s energy, life as we know it could not exist on our home planet.

2. Feb. 2024 · Near the sun’s equator, magnetic field lines make small loops near the surface. Magnetic field lines that flow through the poles extend much farther, thousands of kilometers, before returning to the opposite pole. The sun rotates around its own axis, just like Earth. The sun rotates counterclockwise, and takes between 25 and 35 days to ...

21. Jan. 2019 · Earth’s distance from the Sun (center-to-center) varies from 147,098,074 km at perihelion (closest) to 152,097,701 km at aphelion (most distant). Therefore, the difference is 5 million kilometers!. The perihelion happens around January 4th, when the solar declination is about -23°, therefore, the latitude of the subsolar point is around 23 ...
