Earth is situated within a complex hierarchy of organization in the universe, primarily as part of the solar system, which includes the Sun and other celestial bodies. The solar system is located within the Milky Way galaxy, one of billions of galaxies in the observable universe. This hierarchy can be summarized as follows: Earth → Solar System → Milky Way Galaxy → Local Group of Galaxies → Virgo Supercluster → Observable Universe. Thus, Earth occupies a small but significant position within this vast cosmic structure.
Ptolemy believed that Earth was the center of the universe, with the Sun, Moon, and other planets revolving around it in circular orbits. This geocentric model of the universe was the prevailing view in Western civilization for over a thousand years.
The answer is not determinable both because scientists have not determined the exact volume of the universe and because the universe is always expanding.
No, the term "Earth" specifically refers to the planet we live on. The universe is the vast expanse of all known and unknown matter, energy, space, and time.
According to Ptolemy, the Earth was at the center of the universe in a geocentric model, with the Sun, Moon, planets, and stars revolving around it in complex orbits. This view dominated for centuries until Copernicus proposed a heliocentric model, placing the Sun at the center of the universe and asserting that the Earth and other planets orbit around it. Copernicus's model simplified the understanding of celestial movements and challenged the long-held Ptolemaic system.
Earth's aphelion position occurs approximately six months after its perihelion position. Perihelion, when Earth is closest to the Sun, typically occurs around early January, while aphelion, when Earth is farthest from the Sun, usually takes place in early July. This timing is a result of Earth's elliptical orbit around the Sun.

3rd planet from the sun
It's flat. It is the center of the Universe.
No. It cannot escape the Earths gravity.
The sky is the atmosphere of Earth and any visible part of the universe, as observed from Earths surface.
