During the course of a 13-second exposure, the International Space Station makes a trail of light in the sky as the station ...

That means the spacecraft moved from the ecliptic plane, and tilted its orbit to 17 degrees in relation with the Sun's equator.

Breaking free of the ecliptic plane is an immensely fuel-intensive maneuver, and until now, only the ESA/NASA Ulysses mission, which launched in 1990 and ended in 2009, has flown high enough to ...

Astronomers describe Mercury as an "inferior planet", because its orbital path around the sun is much closer than that of Earth. As a result, Mercury never strays far from the sun ...

Spica is magnitude 1 and sits close to the ecliptic, the plane of the solar system, which is also near the Moon’s orbit through our sky.

The moon's orbit is tilted 5.15 degrees with respect to the ecliptic, or the plane of the Earth around the sun.

Spica is magnitude 1 and sits close to the ecliptic, the plane of the solar system, which is also near the Moon’s orbit through our sky.
