Asteroid 2024 BJ, which astronomers detected earlier this month, will zoom within 220,000 miles of Earth tomorrow, or closer to us than the average distance to the moon.

Watch the Bulletin of the Atomic Scientists' annual Doomsday Clock announcement to find out if 2024 is the year we creep closer than ever to a human-made apocalypse.

It may initially seem like a simple question, but determining which planet is closest to Earth is surprisingly tricky and can have multiple correct answers.

Scientists have identified three definitive supercontinents in Earth's history and predict the landmasses we live on today will come together again in the future.

Earth and other terrestrial planets probably use their gravitational forces to tear apart asteroids ― but this creates more streams of smaller asteroids.

Our solar system has been orbiting the Milky Way's black hole heart for 4.6 billion years. But it is hard to pin down exactly how many trips around the galaxy our sun has made during that time.

Intense pressure and sweltering temperature would accompany a trip down through Earth's layers and out through the other side. However, this trip would be possible only in science fiction.

Asteroids with different spins and bonding strengths may be responsible for the vast variety of impact craters on Earth, including Arizona's Barringer Crater, new simulations show.

The first life-forms capable of evolution could have appeared just moments after the Big Bang, a physicist explains.

We worked out how many trips each of the solar system's eight planets has taken around the sun over the past 4.6 billion years.
