Planetary Science

Many people say that there are only eight planets in our solar system since Pluto was demoted to a dwarf planet. Astronomers mostly consider planets and dwarf planets together when they count the number of planets in the solar system. A few more dwarf planets have been found, or at least put in the category of dwarf planets. More can be expected.

The 8 planets:

1. Mercury

2. Venus

3. Earth

4. Mars

5. Jupiter

6. Saturn

7. Uranus

8. Neptune

The 5 dwarf planets:

1. Ceres (an asteroid)

2. Pluto

3. Haumea (Kuiper Belt Object)

4. Makemake (Kuiper Belt Object)

5. Eris (Kuiper Belt Object)

Well, darling, the brother planet to Earth is technically Venus. They're both rocky planets and are similar in size, but Venus is just a little hotter and has a bit of an attitude problem with its thick atmosphere of carbon dioxide. So, if Earth and Venus were siblings, Earth would be the responsible one while Venus would be the rebellious troublemaker.

Yes, but usually not in liquid form. Most planets, and many moons and comets have water. But on the hot planets Mercury and Venus, and the gas giants Jupiter and Saturn, it is only a trace vapor. On Uranus and Neptune, it is a superheated ionized slush near the core. On Mars, Pluto, and most moons, it exists as ice. The only likely locations for liquid water is beneath the surface of Jupiter's moons Europa and Callisto, and Saturn's moon Enceladus (where it may be forming erupting geysers).

You would need lots of food and something to keep you warm. You would need a building of some sort of hest which is not yet here in England. It would also have to be strong because of the wind and you would need air from earths you would need an oxygen tank of course since there is no oxygen besides helium and hydrogen that is the main thing i would first bring to Neptune.But we can't bring heat since Neptune is made out of methane

Venus is classified as a terrestrial planet. Terrestrial planets are rocky planets with solid surfaces, similar to Earth. Venus is often referred to as Earth's "sister planet" due to its similar size and composition. Gas giants, on the other hand, are planets primarily composed of gases such as hydrogen and helium, like Jupiter and Saturn.

Yes. It the earth distorts the light from the sun at first, causing the moon to turn a reddish colour. If it's a good lunar eclipse then the moon will go dark as the earth puts the moon into a shadow.

The Autumnal full moon, known as the "Harvest Moon" or "Hunter's Moon" elsewhere, is still called a Comanche Moon in Texas because the Comanches were known to raid settlements then.

There is no real relationship between their diameter and distance from the sun, except that you could say that the four outer gas planets are much bigger than the four inner rocky (or terrestrial) planets.

Ross 154 is a red dwarf star located approximately 9.693 light-years away from Earth. A light-year is the distance that light travels in one year, which is about 5.88 trillion miles. Therefore, the distance from Ross 154 to Earth is roughly 57 trillion miles.

If there were no moon, there would be no tides. There would also be complete darkness at night, except for starlight.

Astronomy would probably be less advanced if there never was a moon. The sight of the moon has excited wonder and curiosity throughout the ages.

The moon is slowly drifting away from the earth and was once a lot closer but, at less than 4 centimeters a year, it won't be leaving anytime soon!

Jupiter, Saturn, and Uranus are all gas giants in the outer solar system. They have thick atmospheres composed mostly of hydrogen and helium, and they have rings around them, although Saturn's are the most prominent. Additionally, they all have numerous moons, with Jupiter having the most, followed by Saturn and then Uranus.

It isn't. There are slightly more than 365 days in a year. A day it the time it takes for the earth to rotate about its axis. A year it the time it takes the earth to orbit the sun, being roughly how many 'spins' our planet makes on its axis during one full orbit of the sun.

As of now, the only planet people have walked on is Earth. However, astronauts have landed and walked on the Moon during the Apollo missions. No humans have landed on any other planets in our solar system.

To move the sun disc closer to Panashi, you need to adjust the position of the light source in the scene. This can be done by physically moving the light or adjusting its placement in the virtual environment using 3D software. Experiment with different angles and distances to achieve the desired lighting effect.

Well, honey, the gassy planets in our solar system are Jupiter, Saturn, Uranus, and Neptune. They're like the cosmic burpers of the neighborhood, full of hydrogen and helium with a side of sass. So, if you're looking for a place to let one rip without judgment, those are your go-to spots in space.

Because the four inner planets are more rocky than gaseous, while the "gas giant" planets may or may not have any kind of a rocky core.

And the word "terra" means earth or rock. So, "terrestrial".

# Earth # Mercury (see note) # Venus # Mars # Neptune # Uranus # Jupiter # Saturn The measurements I could find for Mercury (CRC Handbook of Chemistry and Physics, 60th Edition) had enough uncertainty to potentially move it either up or down one place in the list.

The sources of light are electrons. When electrons are exited to a higher energy state, they fall back to their base energy level and in doing so release a photon of light. Thus light is produced in conditions where atoms/electrons become excited - places that are hot.

Oh, dude, that's an easy one. "Our planets" is just the phrase "our planets" spelled backward. So, if you flip "our planets" around, you get "stanetnruo." And if you add five P's in front of that, you get "PPPPPstanetnruo." Voila!

Some food or snacks named after planets include Mars chocolate bars, Jupiter grapes, and Galaxy chocolate. These products often play on the planetary names to create a fun and interesting association with the food item.

The reason we don't feel the earth spin is because you can only experience spinning at a constant velocity as the centrifugal force, and on the surface of Earth, the centrifugal force is very weak compared to gravity. Gravity is pushing us down toward the center of the earth at roughly 9.8 m/s^2. If you are standing on the equator you have a centripetal acceleration of roughly 0.034 m/s^2, causing a centrifugal force of of your mass times the centripetal acceleration.

So you're constantly being pushed down at roughly 9.8 m/s^s and constantly being pushed up at roughly 0.034 m/s^2. Like all bodies under multiple forces, you only experience the NET force, which is pushing you down. That's why you don't feel the earth spinning.

Meteoroids can orbit the Sun at various distances. Some can be as close as a few million kilometers, like those in the asteroid belt between Mars and Jupiter, while others can travel much farther out in the solar system. The distance of a meteoroid from the Sun depends on its specific orbit within the solar system.

The four gas giants in our solar system (Jupiter, Saturn, Uranus, Neptune) are similar in that they are all composed mainly of hydrogen and helium, have thick atmospheres, and lack solid surfaces. They also have numerous moons and ring systems.
