What are Jupiter's minor gases?
The composition of Jupiter's atmosphere is as follows:
Major gases:
- Molecular hydrogen (H2) - 89.8% (2.0%)
- Helium (He) - 10.2% (2.0%)
Minor Gases (approximately, in ppm):
- Methane (CH4) - 3000
- Ammonia (NH3) - 260
- Hydrogen Deuteride (HD) - 28
- Ethane (C2H6) - 5.8
- Water (H2O) - 4
Do planets and the sun interact?
Yes, planets and the sun interact through gravitational forces. The sun's gravity keeps the planets in orbit around it, while the planets' gravity tugs on the sun, causing it to wobble slightly. Additionally, the sun's energy and solar wind affect the planets' atmospheres and magnetic fields.
Were all the planets formed at the same time?
Only God knows.
A2. The whole Solar system is believed to have formed at roughly the same time, about 4.5x109 years ago. Much of its materials came from previous super novas.
The Earth had a brush with a similar sized planet soon after initial formation, and from the debris, the Moon and Earth were constructed. This other planet we call Theia.
What is the motion of one object around another?
In planetary terms, when referring to the motion of planets and moons etc. the motion is describes as orbiting. Moons are on orbit around planets, while the planets are in orbit around the sun. An orbital motion.
What is one way to identify trends in the whether?
Here are a few steps to identify patterns in weather:
- one way is use a thermometer, a barometer, anemometer, and a rain gauge
- use a science notebook and record the weather pattern
- you may want to graph it to make it easier
A star system in which on star blocks the light from another is called?
"Occulting binary". The word "occult" means hidden or in shadows; if a binary star's orbital plane happens to be exactly through the Earth's path, we might see two stars when they're separate and then see one of the stars disappear behind (or in front of) the other.
What does lunar and solar mean?
Lunar refers to the moon, or something having an association with the moon. It comes from the Latin root word luna. A related term is loony, which refers to a person that acts strangely, suggesting that they are under the influence of the moon.
What is the most gassiest planet?
Saturn is known to be the most gaseous planet in our solar system. It is primarily made up of hydrogen and helium gases.
How long does it take for the moon to spin around itself?
It takes about 27.3 days for the Moon to spin once on its axis, which is the same amount of time it takes to complete one orbit around the Earth. This synchronous rotation causes the same side of the Moon to always face Earth.
Which outer planets rotate on their sides?
Uranus is the only outer planet (and only planet in our solar system) that rotates on its side.
What are the giant planets mostly made of?
The giant planets in our solar system, such as Jupiter and Saturn, are mostly made of hydrogen and helium, with smaller amounts of other elements like methane, ammonia, and water. These planets have thick atmospheres and lack a solid surface.
An average star such as your sun will eventually end up as?
An average star like the Sun will eventually exhaust its nuclear fuel and expand into a red giant before shedding its outer layers to form a planetary nebula. What remains will be a dense core called a white dwarf, which will gradually cool over billions of years.
Will people ever inhabit the plant mars?
It is possible that humans may one day inhabit Mars, with plans currently in progress by various space agencies and companies to send astronauts to the red planet. However, significant technological advancements and logistical challenges need to be overcome before this can become a reality.
What in the solar system starts with Q?
quasar : a very bright, very distant object, similar to a star
Pegasi are mythical creatures and their alignment as good or evil is subjective and can vary depending on the context or story being told. In general, pegasi are often portrayed as noble and benevolent creatures in mythology and fantasy literature.
How many planets rotate around the sun?
There are eight recognised major planets which orbit The Sun. Starting nearest to the Sun and travelling outwards the planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
When will nibiru be visible all over earth?
Nibiru is said to have been seen somewhere behind the sun. You can see it in Antarctica at this time. Or so the people who claimed to have seen it have said. I can assure you that if a brown dwarf star planet thing was heading twards the inner solar system, we could see it everywhere by now. And especially not if it was due in 2012. If it was real, it would make appearance some time in late 2015 early 2016. Give or take a year . But now there is no proof of Nibiru's being. So.Nibiru is currently behind the minds that made it. ( For now? )
What happens when a super giant explodes?
When a supergiant star explodes in a supernova, it releases a tremendous amount of energy, temporarily outshining entire galaxies. The explosion also disperses heavy elements into space, helping to enrich the interstellar medium and form new stars and planetary systems. The core of the supergiant collapses, forming a neutron star or black hole.
Does the sun set in the south?
At the poles themselves, the sun only rises once and sets once, ... For instance , in Fairbanks, Alaska, which is located south of the Arctic Circle, the sun sets at 12:47 a.m.
so the answer is YES
What planet whose satellites creates significant tidal effects?
Jupiter is a planet whose satellites, particularly Europa, Io, and Ganymede, create significant tidal effects due to their strong gravitational interactions. These tidal forces lead to phenomena such as volcanic activity on Io and potential subsurface oceans on Europa and Ganymede.
Which planet has an acidic atmosphere?
the planet that has acidic rain is planet unknown lol if u have a ps3 and online add me BlazinEagles
Is mars the inner planet or the outer planet?
Mars is an inner planet, located between Earth and the asteroid belt. The inner planets are rocky and terrestrial, while the outer planets are gas giants.
A planet's density can be measured by combining?
the planet's mass and volume using the formula density = mass / volume. By measuring these properties, scientists can determine the density of a planet, which gives insights into its composition and internal structure.
