With an assist from the NEID spectrograph, a team of astronomers have confirmed the existence of exoplanet Gaia-4b—one of the ...

Using data from the European Space Agency’s Gaia mission, scientists have found a brown dwarf, named Gaia-5b, orbiting a low-mass star. Gaia-5b orbits the star Gaia-5, around 134 light-years away from ...

XR flew about 1.37 million miles (2.2M km) away from Earth. The space rock is estimated to be about 300-700 km (248-434 miles ...

Mars, Venus, Jupiter and Saturn should be visible to the naked eye, but get a telescope and you can spot Neptune and Uranus.

Though the planets are always “aligned,” seeing more than four in the sky is more uncommon. February’s lineup is a chance to ...

An asteroid that orbited near Earth for a few months as a mini-moon may be a chunk of the moon that was blasted off by an ...

Scientists have captured faint magnetic signatures resulting from the tidal movement of seawater across the planet — and they might have to wait until 2030 to get another shot at it.

A close encounter with a mysterious interstellar object could explain the current orbits of several of Earth’s largest ...

A team of scientists has proposed a groundbreaking theory suggesting that a massive interstellar object—potentially eight times the size of Jupiter—may have dramatically impacted the orbits of ...

2D Simulation of Solar System using pure ES 6. Orbits computed with real coefficients (AU scaled to pixels). Main belt asteroids' eccentricities generated with Rayleigh distribution. Welcome to Space ...

The different speeds of the planets mean that, on occasion, several of them can be roughly lined up on the same side of the Sun. From Earth, if the orbits line up just right, we can see multiple ...

Planetary parade in January: A planetary parade is a colloquial term that applies when four or more planets line up in the night sky at once. Sky watchers will get a good view of some of the planets ...
