In the outer Solar System, far from the light and warmth of the Sun, things can get a little… hinky. There, clusters of rocks have been orbiting in weird loops that some astronomers have attributed to ...
Billions of years ago, a star may have passed incredibly close to our Solar System, triggering a series of cosmic events that led to the creation of the moons around the outer planets and the unusual ...

Scientists revise timeline for rogue star’s solar flyby
Scientists have revised the timeline for the approach of the rogue star Gliese 710, which is now expected to enter the solar ...
Scientists have been trying to find a hypothetical Planet 9 that may exist outside our known solar system based on the unusual orbits of certain dwarf planets. But those orbits might not require a ...

A Soft Collision in the Early Solar System May Explain Mercury’s Giant Metal Heart
Mercury is tiny, barely bigger than the Moon. Its metallic core makes up 70% of the planet’s mass, vastly exceeding Earth’s ...
A new study suggests that a close encounter with a massive interstellar object, possibly eight times the mass of Jupiter, may have significantly altered the orbits of the four outer planets in our ...
A massive interstellar object passing through our solar system during its formative years likely altered the orbits of planets into trajectories observed today, a new study says. Interactions with ...
"It is possible that a planet once existed in the solar system but was later ejected, causing the unusual orbits we see today." Astronomers have discovered a massive new solar system body located ...
If microscopic black holes born a fraction of a second after the Big Bang exist, as some researchers suspect, then at least one may fly through the solar system per decade, generating tiny ...
Every decade or so, at least one microscopic black hole might be flying through our solar system, creating minuscule, detectable gravitational distortions. If astronomers can confirm the existence of ...
An early educational game for learning about the solar system, gravitational pull, and other such things. My Outer Wilds journey had me awash in emotions from fear to joy to sadness. There was one ...
