Planetary Science

There are 8 planets in our solar system. They are Earth, Mars, Venus, Mercury, Jupiter, Saturn, Neptune and Uranus. Originally there were many more, but they could have been thrown out of the solar system or have crashed into the Sun or another planet.

Typical of moons of the outer solar system nearly all of Jupiter's moons are covered in ice. Only Io, the innermost moon is not and that it because it is powerfully volcanic.

If the Sun were to stop rotating, its magnetic field would weaken over time and the Sun's surface would become less active with fewer sunspots and solar flares. This could potentially have effects on Earth's climate and space weather, but it would not cause the Sun to go out or have an immediate impact on life on Earth.

The category of "planets that are between us and the Sun" is "inferior"; in this solar system, from the perspective of Earth, there are two such planets. They are Mercury and Venus.

Rarely - twice in a century for Venus, and about every 15 years for Mercury - those planets pass DIRECTLY between us and the Sun, called a "transit". The next transit of Venus will be in 2012.

A rocket traveling from the Earth to the Moon requires more fuel due to Earth's stronger gravitational pull. The rocket needs to overcome Earth's gravity to escape its orbit, which requires a significant amount of energy compared to landing and taking off from the Moon, where the gravitational pull is weaker.

Advantages: Measuring parallax from Pluto allows for a large baseline, providing a more accurate measurement of nearby stars. This can help determine the distances to stars more precisely.

Disadvantages: The long distance from Pluto to Earth can result in a small parallax angle, making measurements more challenging and less accurate. Additionally, Pluto's orbit can introduce complications in consistently observing the same stars.

Mars does. A day on Mars is 24 hours, 39 minutes and 35 seconds, which is slightly longer than the roughly 24 hour day experienced on Earth.

The relative motion between the observer and wave source causes an apparent change in frequency which is known as Doppler Effect. On combination with identification of spectra, it can also be used to find if the start is moving away or towards the earth, When there is shift in lines of spectra towards the red end of visible spectrum the star is said to be travelling away from the earth.

No, Yusuke from Yu Yu Hakusho does not have the ability to destroy planets. While he possesses immense spiritual power and strength, his abilities are limited to fighting opponents on Earth and in the spirit world.

The innermost layer of the meninges is called the pia mater. It is a thin, delicate membrane that is located directly on the surface of the brain and spinal cord, providing protection and support.

Planetary science is the study of planets, moons, and other celestial bodies in our solar system and beyond. It involves understanding their formation, composition, geology, atmospheres, and potential for hosting life. Planetary scientists use a combination of observations, laboratory experiments, and theoretical models to explore these cosmic objects.

A light-year is the distance light travels in one year. Light has a speed of about 300,000 kilometers per second, therefore, every light year is about 9.5 x 1012 (9.5 trillions) of kilometers.

One common mnemonic for remembering the colors of stars in order of decreasing temperature is "Oh Be A Fine Girl, Kiss Me," which stands for O - blue, B - blue-white, A - white, F - yellow-white, G - yellow. Another mnemonic is "Please Excuse My Dear Aunt Sally" with the colors in the reverse order.

As the moon gets further and further away, the gravitational force between the Earth and the Moon decreases. Because the Moon is not being attracted but being pushed away from the Earth. If the gravitational force would have increased, the moon would come closer and closer to the Earth.

When small stars get old, they become white dwarfs. This happens after they have exhausted their nuclear fuel and shed their outer layers. Eventually, the core collapses to form a dense, Earth-sized remnant known as a white dwarf.

The Earth's gravitational attraction prevents gasses from escaping into outer space.

NASA's Mariner 4 was the first spacecraft to slow itself and change its orbit by deliberately skimming through the atmosphere of another planet, which was Mars in 1965. This close approach allowed it to collect valuable data and images of the Martian surface as it flew by.

An eclipse is a celestial event where one astronomical body moves into the shadow of another. The most common types are solar eclipses, when the Moon passes between the Earth and the Sun, and lunar eclipses, when the Earth passes between the Sun and the Moon. The shape of an eclipse can vary depending on factors like the alignment of the three bodies and their relative distances.

Anyone can see beyond our galaxy - even with the naked eye. There are three galaxies that can be seen with the naked eye: M31 (the Andromeda Galaxy), the Large Magellanic Cloud, and the Small Magellanic Cloud. The latter two can't be seen from the northern hemisphere, though.

Because there is no gravity on the moon so it makes it slower to get back to the Earth. On the Earth since there is gravity it takes us a shorter amount of time to launch into space.

A group of planets revolving around a star is called a solar system. Each planet orbits the star in the center of the system and together they form a celestial family held together by gravity. The most well-known solar system is our own, which consists of eight planets orbiting the Sun.

If the Earth was a pea, then the Sun would be about the size of a basketball.

At that scale, the Earth would be 107 feet away.

Mars would be a peppercorn and Jupiter would be a ping pong ball, 555 feet away.

Hydrogen, Helium , Methane and Deuteride are the main gases found on the planet Uranus.
