Objects outside the solar system

Are there any planets outside the Solar System?

"Until 30 years ago, we didn''t know of any planets outside the solar system, all we knew of were the planets in the solar system," said Madhusudhan, "But, as soon as exoplanets were discovered, that opened an entirely new window, into the Universe and its other planetary systems."

Astronomy: The Solar System

The Solar System centers around the Sun and includes all the planets, Kuiper belt - The Kuiper belt is a region of thousands of small bodies that exists outside the orbit of the planets. Objects in the Kuiper belt consist of "ices" such as ammonia, water, and methane.

Did extrasolar planets exist?

There was no evidence to suggest that extrasolar planets, or exoplanets for short, didn''t exist, nor were there hints that the solar system was in any way unique in the Milky Way. But until the very end of the 20th century, astronomers had been frustrated by the lack of direct evidence of worlds beyond the influence of our star.

Exoplanet

An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917 but was not then recognized as such. minimum mass/size required for an extrasolar object to be considered a planet should be the same as that used in the Solar System. Substellar objects with true masses

Are planets outside the solar system''super-Earths'' or''sub-Neptunes''?

When it comes to the categorization of these objects, humanity''s solar system bias is evident. That means worlds outside the solar system are labeled as "Super-Earths, hot Jupiters, and sub-Neptunes" but these planets can be radically different from those of our planetary systems, meaning that they can come in a startling array of forms.

Is it possible to find exoplanets in other solar systems?

Macintosh: Many people thought that other solar systems were like our own – a few small rocky planets closer to the sun, and some giant planets further out – and that it would, therefore, be nearly impossible to find exoplanets because our tools aren''t sensitive enough to see into those kinds of systems.

In Depth | Sun – NASA Solar System Exploration

The Sun orbits the center of the Milky Way, bringing with it the planets, asteroids, comets, and other objects in our solar system. Our solar system is moving with an average velocity of 450,000 miles per hour (720,000 kilometers per hour). Outside the heliosphere is interstellar space. The core is the hottest part of the Sun.

Solar System Facts

Our solar system includes the Sun, eight planets, five dwarf planets, and hundreds of moons, asteroids, and comets. This is a ring of icy bodies, almost all smaller than the most popular Kuiper Belt Object – dwarf planet Pluto. Beyond the fringes of the Kuiper Belt is the Oort Cloud. This giant spherical shell surrounds our solar system.
