What does not belong planet galaxy sun moon?

The sun does not belong in the group of planet, galaxy, and moon. While planets and moons are celestial bodies that orbit around stars, a galaxy is a vast system containing stars, planets, and other celestial objects. The sun is a star and is fundamentally different from the others listed, which are not stars.

How do you figure outer force and inner force?

Outer force refers to external influences acting on a system, such as gravity, friction, or applied loads, which can be calculated based on the context and conditions of the system. Inner force, on the other hand, is the internal resistance or reaction forces within a material or structure, often determined using principles from mechanics, such as equilibrium equations or material stress-strain relationships. To analyze both, you typically start with a free-body diagram, identify all forces acting on the system, and apply Newton's laws or other relevant equations. This process helps to quantify the effects of both outer and inner forces.

The group that believed their system of cooperating communities was better than any other was the Utopians. This term often refers to various groups throughout history, particularly in literature, that envisioned an ideal society based on cooperation, equality, and communal living. They typically critiqued existing societal structures and proposed alternative models that emphasized harmony and shared resources. Their ideals often inspired social movements and experiments aimed at creating more equitable communities.

How lond does nepture take to rotate on its oxis?

Neptune takes about 16 hours to complete one rotation on its axis. This rapid rotation results in a day on Neptune being significantly shorter than a day on Earth. Despite its large size, Neptune's quick rotation contributes to its dynamic atmosphere and weather patterns.

Does the world revolve around money?

While money plays a significant role in modern society, influencing economies, lifestyles, and relationships, it does not solely define the world. Many people prioritize values such as love, community, and personal fulfillment over financial gain. Additionally, cultural, social, and ethical considerations often drive human behavior and decision-making beyond mere monetary concerns. Thus, while money is an important factor, it is not the sole determinant of how the world operates.

What is earths orbits using Kepler's law?

Earth's orbit around the Sun follows Kepler's laws of planetary motion, specifically as an elliptical path with the Sun at one focus, as described in Kepler's First Law. According to Kepler's Second Law, Earth sweeps out equal areas in equal times, meaning it moves faster when closer to the Sun and slower when farther away. The Third Law states that the square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit, allowing us to compare Earth's orbit with those of other planets. This framework accurately describes the dynamics of Earth's yearly journey around the Sun.

Why did the gas giants become so huge?

Gas giants became huge primarily due to their ability to accumulate massive amounts of gas and ice during the early stages of planet formation. Their strong gravitational pull allowed them to attract and retain lighter elements like hydrogen and helium, which are abundant in the protoplanetary disk. Additionally, their formation near the outer regions of the solar system, where cooler temperatures favored the condensation of volatile materials, contributed to their large sizes. This process led to the formation of massive cores that could capture and hold onto significant gas envelopes, resulting in the gas giants we see today.

What Object that orbits the sun is round and cleared the area of it's orbit?

The object that orbits the Sun, is round, and has cleared the area of its orbit is a planet. An example of such a celestial body is Earth. According to the International Astronomical Union's definition, a planet must be in orbit around the Sun, have sufficient mass for a nearly round shape, and have cleared its orbital path of other debris.

What do you call a natural celestial object made up of dust and gasses that orbits around thr sun?

A natural celestial object made up of dust and gases that orbits around the Sun is called a comet. Comets typically have a nucleus of ice and dust, and when they approach the Sun, they can develop a glowing coma and a tail due to the sublimation of their icy components.

What was Laplace's hypothesis that states the planets condesend?

Laplace's hypothesis, also known as the nebular hypothesis, posits that the solar system formed from a rotating cloud of gas and dust. As this cloud collapsed under its own gravity, it began to condense, leading to the formation of the Sun at its center and the planets in orbit around it. This process explains the orderly motion of the planets and their nearly circular orbits, resulting from the conservation of angular momentum during the cloud's collapse.

Do all the outer planets have the names of Roman gods?

Yes, all the outer planets in our solar system are named after Roman gods. Jupiter is named after the king of the Roman gods, Saturn after the god of agriculture, Uranus after the god of the sky, and Neptune after the god of the sea. These names reflect the influence of Roman mythology on astronomical naming conventions.

What is the seventh hottest planet?

The seventh hottest planet in our solar system is Uranus. Despite being farther from the Sun than other planets, it has a unique atmosphere that traps heat, giving it surprisingly high temperatures, particularly in its lower atmosphere. Uranus's extreme tilt and lack of significant internal heat contribute to its overall temperature profile, making it hotter than some closer planets.

Who has done missions in outer and inner space?

Numerous organizations and space agencies have conducted missions in both outer and inner space. NASA is perhaps the most well-known, having launched missions to planets like Mars and Venus while also conducting deep space explorations, such as the Voyager missions. The European Space Agency (ESA) and private companies like SpaceX have also undertaken missions in space. Additionally, robotic missions, such as those from the Mars rovers and the Hubble Space Telescope, have significantly contributed to our understanding of both inner and outer space.

What direction do the planets turn on their axis?

Most planets in our solar system rotate counterclockwise on their axes, which is known as prograde rotation. However, Venus and Uranus have unique rotations; Venus rotates clockwise, or retrograde, while Uranus is tilted on its side, causing it to rotate on its side relative to its orbit. This means that the direction of rotation can vary significantly among the planets.

What is our solar system located in the?

Our solar system is located in the Milky Way galaxy, specifically in one of its spiral arms known as the Orion Arm or Orion Spur. This region is situated about 26,000 light-years from the galactic center. The Milky Way is a barred spiral galaxy that contains billions of stars, including our Sun, and is part of a larger group of galaxies known as the Local Group.

What planets move in a retro grade motion?

All planets in our solar system can exhibit retrograde motion, which is an apparent backward movement against the background stars as observed from Earth. This effect is most noticeable with the outer planets like Jupiter, Saturn, Uranus, and Neptune, as well as the inner planets Mercury and Venus. Retrograde motion occurs due to the relative positions of Earth and the other planets in their orbits around the Sun. It's important to note that this is an optical illusion rather than an actual reversal in the planets' orbital paths.

What is a cause of daily variations in temperature on a planet's surface?

Daily variations in temperature on a planet's surface are primarily caused by the rotation of the planet. As the planet spins on its axis, different areas are exposed to sunlight, leading to warming during the day, while areas that are not illuminated experience cooling at night. Additionally, factors such as cloud cover, humidity, and local geographical features can influence how much heat is absorbed or retained, further contributing to temperature fluctuations.

Who believed that everything in the heavens moved in circles?

The belief that everything in the heavens moved in circles is primarily attributed to the ancient Greek philosopher Aristotle and later reinforced by the astronomer Claudius Ptolemy. Aristotle posited that celestial bodies moved in perfect circular motions, reflecting the divine nature of the heavens. Ptolemy's geocentric model further elaborated on this view, proposing a system of epicycles to explain the observed planetary motions while maintaining circular orbits.

How would these gravity forces change if the Earth was much closer to the Sun?

If the Earth were much closer to the Sun, the gravitational force between the two bodies would increase significantly due to the inverse square law of gravitation. This means that the gravitational attraction would be stronger, resulting in a higher orbital velocity for Earth. Consequently, the Earth would experience more intense solar radiation and heat, potentially altering its climate and ecosystems. Additionally, the increased gravitational pull could affect the stability of Earth's orbit and its relationship with other celestial bodies in the solar system.

What is the area of the picture that appears closest to the viewer called?

The area of the picture that appears closest to the viewer is called the "foreground." It typically contains the most detail and draws the viewer's attention, often featuring the main subjects of the artwork. In contrast, the background is further away and less detailed, providing context for the scene.

Is orbital radius the same as distance from the sun?

No, orbital radius and distance from the Sun are not always the same. The orbital radius refers to the average distance of an object in orbit around the Sun, such as a planet, from the Sun. However, because orbits can be elliptical, the actual distance from the Sun can vary at different points in the orbit, being closer at perihelion and farther at aphelion.

A planet's ability to retain an atmosphere depends on what?

A planet's ability to retain an atmosphere primarily depends on its gravitational pull, which must be strong enough to hold onto gas molecules. Additionally, the planet's temperature plays a crucial role; higher temperatures can increase the kinetic energy of gas molecules, making them more likely to escape into space. The presence of a magnetic field can also help protect the atmosphere from solar wind stripping. Finally, the planet's composition and surface conditions can influence atmospheric retention over geological timescales.
