Our Solar System

Our solar system is made up of a star—the Sun—eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto. Planets, asteroids, and comets orbit our Sun. They travel around our Sun in a flattened circle called an ellipse. It takes the Earth one year to go around the Sun. Mercury

Hypothetical Planet X

Pluto was considered the ninth major planet in our solar system until the definition of "planet" was changed by the International Astronomical Union (IAU) in 2016. This new definition reclassified Pluto as a dwarf planet. Even before the IAU action, back when it was discovered, it was thought that Pluto was as massive as Earth.

6 FAQs about [New planets in our solar system]

Can a planet orbit another star?

Lee esta historia en español aquí. Researchers confirmed an exoplanet, a planet that orbits another star, using NASA’s James Webb Space Telescope for the first time. Formally classified as LHS 475 b, the planet is almost exactly the same size as our own, clocking in at 99% of Earth’s diameter.

How did scientists find the two new planets?

But the scientists also used data from ground-based telescopes to confirm the existence of the two new planets. These telescopes measured the “wobble” of the star, caused by the gravitational tugs from orbiting planets, which yields the planets’ mass.

Can astronomers see a planet outside our Solar System?

For the first time, astronomers have used NASA’s James Webb Space Telescope to take a direct image of a planet outside our solar system. The exoplanet is a gas giant, meaning it has no rocky surface and could not be habitable.

How many planets are there beyond our Solar System?

Not so long ago, we lived in a universe with only a small number of known planets, all of them orbiting our Sun. But a new raft of discoveries marks a scientific high point: More than 5,000 planets are now confirmed to exist beyond our solar system. Astronomers have now confirmed more than 5,000 exoplanets – planets beyond our solar system.

Do rogue planets orbit other stars?

Most of them orbit other stars, but some free-floating exoplanets, called rogue planets, are untethered to any star. We’ve confirmed more than 5,600 exoplanets out of the billions that we believe exist. Most of the exoplanets discovered so far are in a relatively small region of our galaxy, the Milky Way.

Could a ninth planet make our Solar System more similar?

In terms of understanding more about the solar system’s context in the rest of the universe, Batygin says that in a couple of ways, this ninth planet that seems like such an oddball to us would actually make our solar system more similar to the other planetary systems that astronomers are finding around other stars.
