Planetary Science

Yes, Shapley used the distribution of globular clusters in the galaxy to show that the center of the Milky Way was located much farther away than previously thought. By studying the positions and distances of these clusters, he was able to demonstrate that the Sun was not at the center of the galaxy.

A very small percentage. The total mass of the four inner planets is around 0.00059% of the total mass of the solar system. This is around 6 millionths.

The sun makes up around 99.85% of the total solar system mass, while the gas giant planets make up most of the remaining mass.

Certainly, a planetary core can be cold. The heat of our own planetary core is the result of radioactive decay of various elements in the core and mantle, but eventually that heat source will be used up, and the residual heat will gradually leak away into space. There could be other planets which never had much or any abundance radioactive content in the first place.

The Sun spins more than 4 times as fast (at its equator) as the Earth does. The Sun's speed is 7189 km/hr (4467 mph) compared to Earth at 1674 km/hr (1040 mph).

Planets found outside our own solar system are called exo-solar planets or exoplanets. These are in orbit around other stars. It's ver difficult to detect them due to the distances involved, but with modern techniques, over 500 have been confirmed.

A star's internal temperature can vary depending on its size and age, but in general, the core temperature of a star like our sun is around 15 million degrees Celsius. This high temperature is necessary for nuclear fusion to occur and sustain the star's energy production.

The commonality shared by Jupiter, Neptune, and Saturn is that they are all gas giants in our solar system, composed mostly of hydrogen and helium. They also have rings around them and multiple moons.

Uranus is considered to be quite different from the other planets in our solar system due to its unique sideways rotation and extreme axial tilt of nearly 98 degrees. This distinct tilt causes Uranus to essentially roll around the sun on its side, unlike the other planets which rotate more traditionally on their axes.

Stars move through space due to their orbits around the center of their galaxy, gravitational interactions with other stars, and the expansion of the universe. These motions can be influenced by the collective gravitational pull of other celestial bodies and dark matter in the universe. Additionally, the movement of stars can be affected by internal processes such as nuclear fusion and stellar evolution.

It grows when it moves up a level I think. My boonie is on level 0

It grows when you feed it, my boonie is on level 3 but is still the same size as when it started, and i havent yet leveled up on the feeding section, i got to level 3 in about 5 mins, but i havent had my boonie that long so i havent been able to feed it, only about 3 times so yeah

add me allypal

that is a question that's somewhat difficult to answer, as there is no one right answer. Many sources offer different answers, and depending on the source, there are 189, 191, 192, 193, 194, 195 or 196 independent countries in the world today.

Some would say gravity, but since the center of the core is effectively null gravity due to all of the mass of the earth located equidistant from it in all directions, then I think the pressure at the core is considerably lower than others estimate. probably the highest pressures would not be at the core, but at some point between the core and the mantle, some of this depends on a liquid core or a solid core model...how can a solid be pressurized internally if it is free-floating at the center of the mass of a planet? You know, they tell us that the Earth's core is molten iron and nickel and that it is a liquid core since the Earth has a strong magnetic field....but don't you remember learning that heat destroys magnetism? And look at the magnetic field lines in the arching solar flares from the sun itself! How can these be magnetic if heat destroys magnetism....why is the sun magnetic if it is made primarily of hydrogen and helium? One scientific question always seems to lead to others...seems like a fractal progression....

Each of the four inner planets has an atmosphere, except Mercury. Mercury is too small and close to the sun for its gravity to sustain a proper atmosphere, although a tenius and unstable exosphere it thought to exist.

It is impossible it PROVE or DISPROVE the existence of God.

Belief in God is a mater of FAITH not science; Thus as the Big Bang, and formation of planets and Suns is a matter of SCIENTIFIC research and not FAITH, it is impossible to provide you with an answer.

If you believe in God then it is correct for you to assume that God ultimately created everything.

If you do not believe in God then, by definition, God did not create the Big Bang, and form planets and Suns.

A year is a measure of the time it takes a planet to make one complete circle (circuit) around the Sun. Each planet in our Solar system has a different length year.

To make things simple, astronomers can use the number of Earth years a planet takes to orbit the Sun once. Everyone understands time expressed in Earth days.

The Earth's orbit is technically an ellipse, but practically speaking it is almost a perfect circle.

The eccentricity measures how much of an ellipse the orbit is, and an ellipse whose eccentricity equals exactly zero is a circle.

The eccentricity of the Earth's orbit is 1/60, which means the Sun is off-centre by one sixtieth of the radius.

The mean radius is 149.6 million km, so the Sun is 2.5 million km off-centre. That means our distance varies from 147.1 to 152.1 million km.

The shape of the ellipse is nearly a circle and in fact the minor axis is 99.986% as large as the major axis

Although the size of the moon has no effect whatsoever, if it is closer then it must go faster or it will crash into the planet. Not quite. It appears to go faster because it has a tighter orbit and therefore less distance to travel than a larger moon further away, like the inside of a racetrack is a shorter distance than the outside. The same is true of planets orbiting a star, but they are all moving at a similar speed.

No, the tilt of the Earth's axis can vary over long time scales due to gravitational interactions with other celestial bodies like the sun and moon. The current tilt of 23.5 degrees is not constant and has changed over geological time.

The extreme gravitational field of the neutron star...an object with typically 4 to 8 times the mass of our sun, packed into a diameter of about eight miles...pulls mass off of any close companion star, which spirals into the neutron star. If the companion star is close enough, it may over time totally disintegrate and be consumed by the neutron star, which itself may become massive enough to finally become a stellar "black hole", an object whose surface escape velocity would be greater than the speed of light, so that nothing, not even light, can escape beyond its "event horizon".

Some notable new exoplanets discovered in the last decade include Proxima b in 2016, TRAPPIST-1 system of seven Earth-sized planets in 2017, and TOI 700 d in 2020, all of which are potential candidates for hosting extraterrestrial life. These discoveries were made using telescopes like the Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS).

The Higgs is the last missing piece of the Standard Model, the theory that describes the basic building blocks of the universe. The other 11 particles predicted by the model have been found and finding the Higgs would validate the model. Ruling it out or finding something more exotic would force a rethink on how the universe is put together. Scientists believe that in the first billionth of a second after the Big Bang, the universe was a gigantic soup of particles racing around at the speed of light without any mass to speak of. It was through their interaction with the Higgs field that they gained mass and eventually formed the universe.

There is no scientific evidence or consensus on when or if Earth will be destroyed. The planet will continue to exist for billions of years, although there may be events like asteroid impacts or natural disasters that could impact life on Earth.

- Venus is often bright enough to see during the daytime, but you have to know

exactly where to look.

- Mercury, Venus, and sometimes Mars, can be seen during twilight at sunrise and sunset,

when the sun is below the horizon but much of the sky is blue.

- Earth is visible at any time of the day or night.
