While the Sun takes 365¼ days to complete one trip around the ecliptic and return to the same position, the Moon zips around this imaginary circle in just under 30 days.

But during the Buck Moon, it will be roughly 94.5 million miles away. In summer, the sun takes a high path across the sky during the day. The moon, on the other hand, takes the opposite path at night.

This was the Solar Orbiter mission’s first high-angle observation campaign of the sun, conducted at an angle of 15 degrees below the solar equator. Just a few days after snapping these images ...

Because of the elevated path the sun takes through the heavens on this date, the Summer Solstice is also the longest day of the year, offering more hours of daylight than any other.

The standstill is an occurence that stems from the moon’s orbit being tilted in relation to both Earth’s equator and the sun’s path across our sky. That tilt slowly shifts over an 18.6-year ...

If this were the dominant factor in determining the equation of time, then the azimuth of the Sun, observed at noon, would be greater than 180 during half of the year and smaller than 180 during ...

For the dwarf planet candidate, one trip around the sun takes over 24,000 years. Its orbit challenges a proposed path for a hypothetical Planet Nine.

Two minor meteor showers — the Southern Delta Aquariids and Alpha Capricornids — peak overnight on Monday (July 29-30), ...
