Study: Earth formed mostly from inner solar system material
Planetary scientists led by Paolo Sossi have determined that Earth assembled almost entirely from material originating in the ...
Our solar system consists of the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, as well as countless asteroids and comets, that are gravitationally bound to the Sun.
Earth and Mars were formed from material that largely originated in the inner Solar System; only a few percent of the building blocks of these two planets originated beyond Jupiter’s orbit. A group of ...
A mysterious interstellar comet — just the third such object ever confirmed to have entered our solar system — streaked past Mars last week. A spacecraft in orbit around the red planet had a front-row ...
Approximately 4.5 billion years ago, a cold cloud of gas and dust buried deep in one of the Milky Way galaxy’s spiral arms started to collapse. From there, gravity worked its magic. The cloud began to ...
This summer, scientists spotted an incredibly rare visitor to Earth’s solar system—a comet, now known as 3I/ATLAS, that entered our solar system from the galaxy beyond and is zipping past the sun at a ...
For years, planetary scientists have argued that some of the material that built Earth must have drifted in from beyond ...

Visit strange, frozen worlds to discover the bizarre ice that forms beyond Earth. Out in the solar system, ice can get bizarre. Visit strange, frozen worlds – from Uranus’s ultra-hot superionic ice, ...
Our solar system is a weird place. Much more than a home to eight planets, it’s filled with a myriad of fascinating other smaller bodies, including moons, asteroids, and comets. In recent decades, ...
