Orbit of the Solar System: 17,200 pc 5.31×10 17: The average diameter of the orbit of the Solar System relative to the Galactic Center. The Sun's orbital radius is roughly 8,600 parsecs, or slightly over halfway to the galactic edge. One orbital period of the Solar System lasts between 225 and 250 million years.

Ignoring the influence of other Solar System bodies, Earth's orbit, also called Earth's revolution, is an ellipse with the Earth–Sun barycenter as one focus with a current eccentricity of 0.0167. Since this value is close to zero, the center of the orbit is relatively close to the center of the Sun (relative to the size of the orbit).
The incoming solar storm arose from a strong flare near “Region 3500” on the Sun, scientists say. Solar storms are known to interfere with the Earth’s magnetic field and cause damages to ...
NASA Earth science satellite fleet as of September 2020, planned through 2023. Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather ...
The sun has been especially active over the last 48 hours. It's released many M-class solar flares as well as an X-class flare — the most powerful type.
An ancient object that hasn't visited the inner solar system in 50,000 years has gained the attention of stargazers across the Northern Hemisphere, and it could end up being one of the biggest ...
The Solar System will remain roughly as it is known today until the hydrogen in the core of the Sun has been entirely converted to helium, which will occur roughly 5 billion years from now. This will mark the end of the Sun's main-sequence life.
NOAA's GOES-R Series of satellites is designed to improve the forecasts of weather, ocean, and environment by providing faster and more detailed data, real-time images of lightning, and advanced monitoring of solar activities and space weather. GOES-17 can collect three times more data at four times image resolution, and scan the planet five ...
