Because they move against the backdrop of stars. The 'fixed' stars are like a canopy that moves across the sky during the course of a year, but the stars remain in place relative to each other, for all practical purposes. These wanderers, the planets, follow their own paths independent of the stars.

Who invented celestial navigation?
Celestial navigation has been used for centuries by various civilizations, but its modern form can be attributed to early astronomers like Hipparchus and Ptolemy. They developed mathematical models to predict the positions of celestial bodies, which sailors later used to navigate the seas.
Why did people study the sky?
People studied the sky to understand celestial patterns, track time, navigate, and predict weather. Studying the sky also allowed early civilizations to develop calendars, agriculture, and mythologies related to celestial bodies.
Did early astronomical observers conform to the expected predictions of the transparent sphere hypothesis?
Early astronomical observers did not always conform to the expected predictions of the transparent sphere hypothesis, as the observation of planetary retrograde motion led to the rejection of this model. The discovery of deviations from perfect circular orbits and other astronomical phenomena challenged the simplicity of the transparent sphere hypothesis held in early astronomy. Modern understanding of celestial mechanics has replaced this simplistic model with more accurate descriptions of planetary motion.
What does planetismals mean?
Planetesimals are small celestial bodies that formed from dust and gas in the early solar system. They are thought to be building blocks for planets and other larger bodies in our solar system. Planetesimals can range in size from a few meters to hundreds of kilometers in diameter.
Why was the astrolabe important for early exploration?
The astrolabe was important for early exploration because it allowed sailors to determine their latitude by measuring the angle of celestial bodies, primarily the sun or stars, above the horizon. This helped them navigate more accurately and chart their course at sea.
Why did early observers call celestial bodies planetes?

How are asteroiods and comets alike?
Asteroids and comets are alike in that they are both heavenly or celestial bodies. Most of them were born early in the formation of the solar system too.

What is primordial heat?
Primordial heat is the residual heat left over from the formation of celestial bodies, such as planets and moons, during their early stages of development. It is generated by the process of accretion and compression of materials in the early solar system, which results in an increase in temperature within the interior of these bodies.

What religion practiced in early Africa?
Africa is a Continent.It's made up of lots of countries. As a whole I would think Animal ism & Worship of the land & celestial bodies.

What are two inventions that aided in early exploration?
Two inventions that aided in early exploration were the compass, which allowed sailors to navigate based on the Earth's magnetic field, and the astrolabe, which helped sailors determine their latitude by measuring the angle of celestial bodies above the horizon.
Why did Early people had ideas about sun stars or moon on their rituals or customs?
Early people observed the sun, stars, and moon in their daily lives, so these celestial bodies became integral to their rituals and customs as symbols of power, natural cycles, and spiritual connection. They believed that these celestial bodies had influence over their lives and held symbolic significance in various cultural practices and belief systems.
Why did early Greek astronomers think that all celestial bodies moved in circular motions?
Not all of them did. The ones who did believe in strictly circular motions were influenced by Aristotle, who may have been the wrong-est person who ever lived.
