Astral visitor may have changed orbital path of solar system planets, says study. Paths of four outer giant planets, Jupiter, Saturn, Uranus and Neptune minorly deviate from ideal orbital shape.

The Solar System might not be as quiet and orderly as we think. Imagine one day looking up and seeing something strange in ...

For about 4.5 billion years, our planet has circled the sun on a stable, rhythmic path. Each of Earth's orbits takes approximately 365.25 days to complete, defining the length of a year. But how ...

That means it sometimes is closer to the sun than Pluto, whose orbital distance ranges from 30 to 49 astronomical units as it travels an elliptical path around the sun.

WASHINGTON >> Scientists have identified an object about 435 miles wide inhabiting the frigid outer reaches of our solar system that might qualify as a dwarf planet, spotting it as it travels on a ...

In a study published Tuesday in the journal Physical Review D, physicists at MIT say the presence of a tiny black hole speeding through the solar system could be identified by the gentle ...

The Vera C. Rubin Observatory is expected to find millions of unknown objects in our solar system, and perhaps even a ...

Our solar system may have a ninth planet after all, ... but the new definition of a planet requires the celestial body to have enough gravity to clear its orbital path from other bodies. ...

Astronomers are proposing a new, more quantitative definition of what makes a planet. The new definition looks more directly at the object's mass — but it would still leave Pluto out of the running.

Each satellite would be fitted with an electrical propulsion system and utilize gravity assists from Venus to maintain its orbital path. According to the paper, this system could maintain ...

Passing Star Nudged Solar System 70,000 Years Ago To figure this out, the team ran several simulations that traced the formation of the Oort cloud and the paths of the individual objects inside it.

Earth’s orbital distance from the Sun is called an astronomical unit. 2017 OF201 is currently located at a distance of 90.5 astronomical units from the Sun, meaning 90.5 times as far as Earth.
