The Fascinating Distances of Solar Imaging

This isn't a close-up image of the Sun.
It's taken from Earth, 149 million kilometers away.

When we see stunning images of the Sun, we often forget just how far these images are captured from. The average distance from the Earth to the Sun is approximately 149 million kilometers, or 93 million miles. Despite this vast distance, modern telescopes and cameras allow us to capture incredibly detailed images of our star from the ground.

This IS a close-up image of the Sun!
The closest possible Sun imaging at the present time is by ESA's Solar Orbiter spacecraft, which approaches the Sun to approximately 42 million kilometers.

ESA's Solar Orbiter is a marvel of modern engineering, designed to get us closer to the Sun than ever before. Launched in February 2020, this spacecraft embarks on a unique journey, swinging past the inner planets to gradually reduce its distance to the Sun. Its closest approach brings it to about 42 million kilometers (26 million miles) from the Sun. At this proximity, the Solar Orbiter can capture unprecedented high-resolution images and gather data, providing insights into solar phenomena that were previously out of reach.

These incredible images and data are crucial for understanding the Sun's behavior, which in turn affects space weather and conditions here on Earth. With every closer approach, Solar Orbiter is helping us uncover the mysteries of our closest star.
