Earth and Other Planets Formed Due to slow combination of material like asteroids and remaning is known to be in kuiper belt and oort clouds then why dont they combine to form planet.
Answers
Explanation:
Both Arrokoth (recently visited by NASA's New Horizons mission) and Pluto are in the Kuiper Belt — a donut-shaped region of icy bodies beyond the orbit of Neptune. There may be millions of these icy objects, collectively referred to as Kuiper Belt objects (KBOs) or trans-Neptunian objects (TNOs), in this distant region of our solar system.

Similar to the asteroid belt, the Kuiper Belt is a region of leftovers from the solar system's early history. Like asteroid belt, it has also been shaped by a giant planet, although it's more of a thick disk (like a donut) than a thin belt.
The Kuiper Belt shouldn't be confused with the Oort Cloud, which is a much more distant region of icy, comet-like bodies that surrounds the solar system, including the Kuiper Belt. Both the Oort Cloud and the Kuiper Belt are thought to be sources of comets.
The Kuiper Belt is truly a frontier in space -- it's a place we're still just beginning to explore and our understanding is still evolving.
