What Is the Planetesimal 98765 ALEKS?

The planetesimal 98765 ALEKS is a rocky and icy object located in the outer Solar System. Scientists classify it as a planetesimal because it formed during the early stages of Solar System development. Unlike planets, planetesimals never became large enough to form into fully developed worlds.

Researchers believe 98765 ALEKS has existed for more than 4.5 billion years. This makes it older than many geological structures on Earth. Because the object stayed mostly unchanged for billions of years, scientists consider it a natural time capsule.

The planetesimal contains frozen compounds, ancient minerals, dust particles, and carbon-rich materials that may hold clues about how the Solar System formed. Some scientists even think objects like 98765 ALEKS could explain how water and organic molecules reached Earth in ancient times.

Before the mission began, astronomers observed the planetesimal using powerful telescopes. They noticed several unusual features:

• A dark surface rich in carbon materials
• Large amounts of frozen ice beneath the outer layer
• Strange reflective regions that suggested metallic compounds
• Slow rotational movement
• Evidence of ancient collisions

These discoveries increased scientific interest in the object. Researchers believed direct samples could reveal information impossible to obtain through telescopes alone.

Why Scientists Wanted Samples From 98765 ALEKS

When a robot spacecraft returned samples from the planetesimal 98765​, scientists gained access to material untouched since the birth of the Solar System. This was extremely valuable for several reasons.

Understanding the Origins of the Solar System

Planetesimals formed during the earliest stages of planetary development. Scientists believe the planets we know today grew from smaller objects colliding and combining over millions of years.

By studying material from 98765 ALEKS, researchers hoped to understand:

• How dust particles formed larger structures
• How early planets gained mass
• What materials existed in the young Solar System
• How chemical reactions evolved over time

The samples provided direct evidence instead of theoretical models.

Learning About Organic Compounds in Space
