Planetary Science

They can turn either direction in either the north or south hemisphere, as they are too small to be affected by the Coriolis Force.

It is highly unlikely for planets to form on another planet. Planets typically form from material surrounding a star, not from existing planets. However, moons can form around planets through processes such as accretion or capture.

Usually, planets do have grounds, though it usually differs. The four inner planets (Mercury, Venus, Earth, and Mars), are solid, or rocky. The heat from the sun solidified them. Outer planets' atmospheres (Jupiter, Saturn, Uranus, and Neptune) are full of gases, BUT, these gases surround the rocky core. So yes, Neptune does have ground, though its not as much as earth.

Jupiter is a gas giant composed mostly of hydrogen and helium, so it does not have a surface where humidity can be measured. The planet's atmosphere is predominantly made up of hydrogen and helium, with small amounts of water vapor, ammonia, methane, and other gases, but it doesn't have a measurable humidity level like we experience on Earth.

No, stars are always present in the sky but they are not visible during the day because of the sun's brightness. As the Earth rotates, different stars come into view at night while others disappear below the horizon.

The fuel needed to travel from Earth to Jupiter will depend on various factors such as the spacecraft design, propulsion system, trajectory, and payload weight. Generally, a mission to Jupiter would require a significant amount of fuel due to its distance from Earth and the need to accelerate to escape Earth's gravity and reach Jupiter's orbit.

There is no newly added planet to the solar system. The last major change to the planetary lineup was the reclassification of Pluto as a dwarf planet in 2006.

Yes, the theme for World Environment Day 2011 was "Many Species. One Planet. One Future." It aimed to promote the protection of biodiversity and emphasize the interconnectedness of all living organisms on Earth in shaping a sustainable future.

Our own galaxy has between 100 and 400 billion stars; there are hundreds of billions of similar galaxies in the OBSERVABLE Universe, and it is believed that the entire Universe is much, much bigger than the observable Universe (how much bigger, is not known). It seems that at least a large percentage of those stars have planets, which means they can be called "solar systems".

Mercury, the closest planet to the sun. Its average distance is around 58 million km ,but this varies a lot. At its closest it can be around 46 million km, and 70 million km at its furthest.

It can't. The Earth is like an enormous gyroscope; it cannot tilt more or less without some titanic external force doing it, and the force required would most likely cause catastrophic damage to the planet. The tilt of the Earth does naturally vary slightly over time; this motion is called nutation. It's a fairly complicated motion with many terms; the largest one amounts to a change of about 17 arc-seconds (about 1/200th of a degree) over a period of 18.6 years.

Spectral class O5 stars remain on the main sequence for around 3-4 million years before they evolve off the main sequence stage. These stars have extremely high luminosities and temperatures, leading to a short main sequence lifetime compared to lower mass stars.

Yes, the fast spinning of a planet can cause bands on it. This is known as zonal wind patterns, where the rotation of the planet creates bands of winds that blow in specific directions. An example of this can be seen on gas giants like Jupiter, where its rapid rotation causes distinct bands of clouds to form.

Yes, the gravitational force exerted by the Sun is much greater than that of the Earth. The Sun's mass is significantly larger than the Earth's, resulting in a stronger gravitational pull. This gravitational force is what keeps the planets in orbit around the Sun.

Pre-Galileo, no planets revolve around earth

23.5 degrees, the same as the "tilt" of Earth's rotational axis in space, the cause of the seasons.

It is hard to know the exact situation before the big impact. However, most objects start with some rotation when they form from coalescing materials, and it seems unlikely that the Earth would have had enough time to slow down enough to have a synchronous rotation.

After a successful run the production of Saturn cars was stopped in 2009 after a much sought after deal between GM and Penske Automotive group fell through.

Just like Pluto they are considered Planetary Bodies, but don't have the formal distinction of being a Planet.

Our Sun is most definitely a star. The Sun's stellar classification, based on spectral class, is G2V, and is informally designated as a yellow dwarf. In the spectral class label, G2 indicates its surface temperature of approximately 5505 °C, and V indicates that the Sun, like most stars, is a main-sequencestar, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium.

As for the moon, it is simply the Earth's natural Satellite, and the 5th largest satellite in our Solar System. It is not considered to be a planet because a planet is a celestial body orbiting a star or stellar remnant which is massive enough to be rounded by its own gravity (and being in the Earth's orbit, the Moon does not fit these criteria; thus being a natural satellite).

The nearest star to the Sun is Proxima Centauri, which is part of the Alpha Centauri star system. It is located about 4.24 light-years away from Earth.

Jupiter spins the third fastest on its axis, with a day lasting about 9.9 hours.

Earth is the only planet known to have only 1 moon.

The giant is called selfish because he doesn't want to share his garden with the children, keeping it for himself and denying them access to play and enjoy themselves. His actions demonstrate an unwillingness to think about others or consider their well-being.

To make Earth habitable, several factors need to be in place: a suitable distance from the sun to maintain a stable temperature, a protective atmosphere to shield against harmful radiation, liquid water for life to thrive, and a magnetic field to protect against solar winds. Additionally, a diverse range of ecosystems and biodiversity contribute to the planet's habitability.
