Planet Nine could be a primordial black hole, new research suggests

The hypothetical Planet Nine, assumed to be lurking somewhere in the outskirts of our solar system, may not be a planet at all. A new study, published September 24 on the arXiv pre-print server, suggests that the mysterious ...

Trans-Neptunian objects suggest that there are more planets in the solar system

There could be at least two unknown planets hidden well beyond Pluto, whose gravitational influence determines the orbits and strange distribution of objects observed beyond Neptune. This has been revealed by numerical calculations ...

Extreme trans-Neptunian objects lead the way to Planet Nine

In the race towards the discovery of a ninth planet in our solar system, scientists from around the world strive to calculate its orbit using the tracks left by the small bodies that move well beyond Neptune. Now, astronomers ...

Herschel observatory's population of trans-Neptunian objects

( —ESA's Herschel space observatory has observed 132 of the known 1400 cold worlds that inhabit a region of the Solar System beyond the orbit of Neptune, some 4.5–7.5 billion km from the Sun.

How we discovered 840 minor planets beyond Neptune – and what they can tell us

Our solar system is a tiny but wonderfully familiar corner of the vast, dark universe – we have even been able to land spacecraft on our celestial neighbours. Yet its outer reaches are still remarkably unmapped. Now we ...

Kepler has caught hundreds of asteroids

Previously, the Kepler space telescope looked straight out from the solar system in a direction almost perpendicular to the ecliptic and the plane of the planets. This way, it could observe the same spot all year long, as ...

Rosetta's comet sculpted by stress

Feeling stressed? You're not alone. ESA's Rosetta mission has revealed that geological stress arising from the shape of Comet 67P/Churyumov–Gerasimenko has been a key process in sculpting the comet's surface and interior ...

Remote sensing for cosmic dust and other celestial bodies

The solar system is full of various small bodies such as planetary moons, main belt asteroids, Jupiter Trojans, Centaurs, trans-Neptunian objects and comets. To study them, scientists typically analyse the radiation they ...

New evidence in support of the Planet Nine hypothesis

Last year, astronomers announced the existence of an unknown planet in our solar system. However, this hypothesis was subsequently called into question as biases in the observational data were detected. Now, Spanish astronomers ...

New data about two distant asteroids give a clue to the possible 'Planet Nine'

The dynamical properties of these asteroids, observed spectroscopiccally for the first time using the Gran Telescopio CANARIAS, suggest a possible common origin and give a clue to the existence of a planet beyond Pluto, the ...
