.All are made of individual particles of rock or ice that orbit in accord with Kepler's laws: inner ring particles orbiting faster, and outer ring particles orbiting slower. b.All have gaps and ringlets, probably due to gap moons, shepherd moons, and orbital resonances. c.All probably look much like they did when the solar system first formed. d.All the particle orbits are fairly circular, near their planet's equatorial plane.
From the Brera Observatory in Milan in the late 1800s, Schiaparelli mapped and named many of the major features of the Planet Mars -- and we still use those naming conventions today. He also mapped a network of what he called "canali" (or channels) on the surface of Red Planet. While later studies proved that these observations were the product of optical illusions, the mistranslation of his word as 'canals' into English lead to widespread speculation about the possibilty of extraterrestrial intelligent life. (So most late 19th and early 20th century tales of Martian invasions -- e.g., Wells' War of the Worlds -- owe a debt to Schiaparelli!) In addition, Schiaparelli contributed to the modern scientific understanding of the relationship between meteor showers and asteroids, and he made early observations regarding the orbits of binary stars and the orbital patterns of Mercury and Venus.
All current scientific evidence suggests that Earth has existed for approximately 4-5 billion years.Question's such as these will have different answers, simply because no one knows.

It is believed that Nicolaus Copernicus first proposed the heliocentric theory.
Nicolaus Copernicus was the scientist who proposed that the planets move around the sun in circular orbits, known as heliocentrism. His theory laid the foundation for modern astronomy and challenged the geocentric model.
Nicolaus Copernicus proposed the heliocentric model of the solar system in the 16th century. He suggested that the Earth rotates on its axis and orbits around the Sun, which was a significant step in understanding the Earth's motion.
Nicolaus Copernicus proposed the heliocentric model with circular orbits of the planets around the Sun in the 1500s. His work, "De revolutionibus orbium coelestium," laid the foundation for the Copernican Revolution in astronomy.
Nicolaus Copernicus proposed that the Sun, not the Earth, was the center of the solar system and that the planets, including Earth, revolved around the Sun in circular orbits. This heliocentric model challenged the prevailing geocentric view of the time.
No Nicolaus Copernicus created it (although the planet's orbits were perfect circles in his model). Isaac Newton expanded on it. After Copernicus, Johannes Kepler stated that the orbits were elliptical. Isaac Newton came up with the theory of universal gravitation.
