**Title: Understanding Object Size Changes in the Early Solar System**

**Question:**
Did objects in the early Solar System get generally smaller or larger? Explain.

**Content:**
In the early Solar System, objects underwent a fascinating evolution in terms of size. Initially, the solar system was a giant molecular cloud composed of gas and dust. Over time, under the influence of gravity, these particles began to collide and stick together, gradually forming larger bodies. This process is known as accretion.

As accretion progressed, small particles formed planetesimals, which are the building blocks of planets. These planetesimals continued to coalesce into protoplanets. As protoplanets grew in mass, they attracted more material through their increasing gravitational pull, further increasing their size.

Hence, objects in the early Solar System generally became larger over time, transitioning from microscopic particles to planetesimals, and eventually forming planets and other celestial bodies. This growth process was a key aspect of planetary formation and the shaping of the Solar System as we know it today.
