Meet 'DeeDee,' a Distant, Dim Member of Our Solar System

Introduction

Our solar system is vast and mysterious, with many objects still waiting to be discovered. One such object is 'DeeDee,' a distant and dim member of our solar system that was recently discovered by astronomers. In this article, we will explore the discovery of DeeDee, its characteristics, and what it can tell us about the history of our solar system.

What is DeeDee?

DeeDee, short for "Distant Dwarf," is a trans-Neptunian object (TNO) located in the Kuiper Belt, a region of the solar system beyond Neptune. It was discovered in 2016 by a team of astronomers using the Dark Energy Camera on the Blanco telescope in Chile.

Characteristics of DeeDee

DeeDee is a small object, with an estimated diameter of around 635 kilometers (395 miles). It is also very distant from the sun, with an average distance of around 92 astronomical units (AU). For comparison, Pluto, another TNO, has an average distance of around 39 AU.

DeeDee's orbit is also highly elliptical, meaning that it is very elongated. Its closest approach to the sun is around 38 AU, while its farthest distance is around 170 AU. This makes it one of the most distant objects in our solar system.

What Can DeeDee Tell Us About Our Solar System?

The discovery of DeeDee is important because it can tell us more about the history and formation of our solar system. TNOs like DeeDee are thought to be remnants from the early solar system, and studying them can give us clues about how the planets formed.

DeeDee's highly elliptical orbit suggests that it may have been influenced by the gravitational pull of other objects in the Kuiper Belt. By studying its orbit and composition, astronomers can learn more about the dynamics of the Kuiper Belt and how it has evolved over time.

Other Discoveries in the Kuiper Belt

DeeDee is just one of many objects that have been discovered in the Kuiper Belt in recent years. In 2015, NASA's New Horizons spacecraft flew by Pluto and its moons, providing us with the first close-up images of these distant objects.

In addition to Pluto, New Horizons also discovered several other TNOs, including Arrokoth, which was previously known as Ultima Thule. Like DeeDee, these objects can tell us more about the history and formation of our solar system.

Conclusion

DeeDee may be a distant and dim member of our solar system, but its discovery is an important one. By studying this small object, astronomers can learn more about the history and formation of our solar system, as well as the dynamics of the Kuiper Belt. As we continue to explore our solar system, we are sure to discover many more fascinating objects like DeeDee.

FAQs

What is a trans-Neptunian object?

A trans-Neptunian object (TNO) is any object in the solar system that orbits the sun at a greater distance than Neptune.

How was DeeDee discovered?

DeeDee was discovered in 2016 by a team of astronomers using the Dark Energy Camera on the Blanco telescope in Chile.

What can DeeDee tell us about the history of our solar system?

DeeDee is thought to be a remnant from the early solar system, and studying it can give us clues about how the planets formed.

What other objects have been discovered in the Kuiper Belt?

In addition to DeeDee, several other objects have been discovered in the Kuiper Belt, including Pluto and its moons, as well as Arrokoth (previously known as Ultima Thule).

Why is the Kuiper Belt important?

The Kuiper Belt is important because it contains many small objects that are thought to be remnants from the early solar system. Studying these objects can give us clues about how the planets formed and how the solar system has evolved over time.
