“[Planetary scientists] have thought our solar system is not standard in its spacings,” says astronomer Juliette Becker of the University of Wisconsin-Madison. In particular, the rocky planets ...

Astronomers have discovered two new exoplanets that are similar to other worlds found in the Milky Way, but are unlike any in our own solar system. The two exoplanets, or planets outside of our ...

Earth has a nearly circular orbit, but some planets outside our solar system, called exoplanets, have very elliptical orbits. UCLA astrophysicists have now measured the shape of the orbits of ...

Each of the planets, labeled b, c, d, and e, has a mass between 20% and 30% of Earth's, making them among the smallest yet detected using the radial velocity method.

Much like the northern and southern lights on Earth, auroras occur when charged solar particles collide with a planet’s ...

2025 — A combination of cosmic processes shapes the formation of one of the most common types of planets outside of our solar system, according to a new ... TOI-1453: Sub-Neptune in System of ...

As per the researchers, even the icy planets in our solar system such as Neptune, Uranus or Jupiter's moon Europa, might have harboured plastic ice VII in the past. The findings could further help ...

"We know from our own solar system that giant planets bring a little bit of chaos to space. They can perturb orbits and give a little bit of extra boost to the velocities of objects, which is all ...

More than just dazzling streaks of light as meteors, these ancient fragments are among the oldest materials in our solar system, originating from planets, asteroids, and comets. Most meteorites ...
