Our Solar System

The Oort Cloud & The Kuiper Belt A spherical "cloud" of comets, known as the Oort Cloud, surrounds the outer reaches of our solar system. The Oort cloud is vast. It starts between 2,000 and 5,000 AU from the Sun and extends out to 50,000 AU. (One AU, or astronomical unit, is the average distance between the Earth and the Sun.)

Oort cloud: What is it and where is it located?

The Oort cloud, sometimes called the Öpik–Oort cloud, is theorized to be a vast cloud of icy planetesimals surrounding the Sun at distances ranging from 2,000 to 200,000 AU (0.03 to 3.2 light-years). The concept of such a cloud was proposed in 1950 by the Dutch astronomer Jan Oort, in whose honor the idea was named. Oort proposed that the bodies in this cloud replenish and keep constant the n

Solar System, in Perspective

Informally, the term "solar system" is often used to mean the space out to the last planet. Scientific consensus, however, says the solar system goes out to the Oort Cloud, the source of the comets that swing by our sun on long time scales. Beyond the outer edge of the Oort Cloud, the gravity of other stars begins to dominate that of the sun.

6 FAQs about [Is the oort cloud in our solar system]

What is the Oort cloud?

The Oort Cloud lies far beyond Pluto and the most distant edges of the Kuiper Belt. While the planets of our solar system orbit in a flat plane, the Oort Cloud is believed to be a giant spherical shell surrounding the Sun, planets and Kuiper Belt Objects. It's like a big, thick bubble around our solar system, made of icy, comet-like objects.

Is the Oort cloud stable?

The Oort cloud is still not stable. Some of the cloud’s inhabitants may get pulled away into the vastness of space, and some objects may also be collected from the neighboring star systems. The Oort cloud is a massive and most distant region of the Solar System, but what is its actual size and location? Let’s try to clear this up.

How did the Oort cloud form?

The Oort Cloud marks the outermost boundary of our solar system, surrounding it in all directions. The Oort Cloud formed through complex processes in the early solar system. Giant planets scattered icy planetesimals into highly elliptical orbits. The Sun’s gravity and galactic tides shaped the cloud over several hundred million years.

Do comets come from the Oort cloud?

Many long-period comets originate from the Oort cloud. Almost all objects that have approached the inner solar system from the Oort cloud are comets made of frozen gas and dust. But in 2022, as Space.com previously reported, researchers identified an unusual rocky object coming from the Oort cloud.

How cold is the Oort cloud?

It consists of billions or trillions of icy chunks ranging from small rocky objects to mountain-sized masses. The Oort cloud appears see-through due to the enormous spacing between objects. Its temperature ranges from -233°C to -173°C, making it one of the coldest regions in our solar system.

What is the Oort cloud made of?

The Oort cloud is made of icy pieces of space debris the sizes of mountains and sometimes even larger. The Oort cloud is where some comets come from.
