Which planet is the only planet on which life is known to exist?

Earth is the only planet in the solar system where life is known to exist. It has a unique combination of conditions, such as liquid water, a stable atmosphere, and a suitable temperature range, that support the diverse forms of life found on our planet.

When all the planets are lined up in a row in the milklyway will it effect earths gravity?

No, the alignment of planets in the Milky Way does not have a significant impact on Earth's gravity. The gravitational pull between planets is determined by their masses and distances, not their alignment. Earth's gravity is mainly influenced by the mass of Earth itself.

How many people are alive and are staying in this planet earth?

As of now, there are approximately 7.9 billion people alive and residing on planet Earth. This number is continuously changing due to births, deaths, and other demographic factors.

What studies the Sun and its interactions with Earth and other planets in the solar system?

The field of heliophysics studies the Sun and its interactions with Earth and other planets in the solar system. It involves understanding solar activity, solar wind, magnetic fields, and their impacts on the space environment surrounding the planets. Scientists use various instruments, satellites, and spacecraft to study these phenomena.

Is there a habitable planet apart from earth?

Truest answer is we don't know.

Extra solar planetary science is still in its infancy. There have been several super Earths discovered in other systems, but it is not certain for those planets support life, of it they would be habitable by humans.

What we do know is that we do not have the technology yet to reach them even if they could support human life.

What would happen if you launched at a faster speed in to orbit?

Depending on the direction in which your speed was pointed, and at

what stage of the launch it was faster, any of these could happen:

-- you would get to orbit sooner

-- you would settle into a smaller, more circular orbit

-- you would settle into a larger, more eccentric orbit

-- you would not orbit at all, but escape the Earth completely and never return

How far is Venus from Earth in feet?

On average, Venus is about 25 million miles away from Earth. To convert this distance to feet, we would need to multiply it by approximately 132,000,000 feet per mile, which would give us a distance of roughly 3,300,000,000,000 feet between Venus and Earth.

How does the Earth's rotation cause temperature differences during day and night?

Temperature difference is not actually caused by the spinning but by a direct result of it, where the sunlight is hitting the surface of the earth and warming it up. When the earth rotates the earth stops warming some of it up and begins to warm up other parts of it. The part no longer being warmed up is now undergoing 'night' and begins to cool down. If the earth rotated the same speed it went around the earth but in the opposite direction it would always be day on one half the earth and uninhabitably hot, while the other side would be just as cold.

What is the inner and outer earth parts?

The inner Earth consists of the inner core, outer core, mantle, and crust. The outer Earth is composed of the atmosphere, hydrosphere (water bodies), lithosphere (solid Earth), and biosphere (living organisms).

How many molecules are there in earth?

42

ok so this person put only 42 molicules in the universe? wrong! there are so many molecules in the universe that not even sientists could figure that out but my guess is that there are billions and zilions of molicules in the universe.

What way earths rotation makes wind curve?

As you may or may not know, there are areas of high and low pressure all over the Earth. Just as water moves from high to low concentration in osmosis, air moves from high pressure to low pressure. This movement is called wind.

Wind is caused on the Earth because of the Sun. The Sun heats up the mantle of the Earth and this makes the warmer air rise above the cooler air. This causes a space that needs to be replaced. Cooler air rushes in to replace this void and "Wind" occurs. Wind is caused also by the same cooling pattern by taking the warmer air around the equator and moving it towards the poles, usually in the form of tropical storms or hurricanes and taking this heat and transferring it to cooler regions.

What is the temperature of earth compared to Saturn?

Because of Earth's orbital location and atmosphere, the temperatures are within a much smaller range than for the gas giant Saturn.

The temperature at the top of Saturn's clouds averages -285° F (-175 °C). This is because the thin gas does not retain heat, and solar radiation at Saturn's orbital distance is minimal. The core of Saturn is much hotter, estimated at 11,700 °C, mainly due to extraordinary pressure and tidal forces in the thickening atmosphere.

On Earth, geothermal heating is negligible, and the planet is heated by the Sun, alternately heating and cooling as it rotates. Atmospheric currents keep the temperature range between -40° and +40° C (-40° to 104°F) for most of the planet, with extremes of -89° and +58°C (-128°F and 136°F).

What is opposite from New Jersey on the planet Earth?

The direct opposite or antipodal point of New Jersey on Earth is in the southern Indian Ocean, near the French Southern and Antarctic Lands. This point is approximately at latitude -40.0 and longitude 140.0.

Why is earth the only planet with life existence?

Earth is unique in having the right conditions for life to exist, such as the presence of liquid water, a suitable atmosphere, and a stable climate. The combination of these factors has allowed life to thrive on Earth, while other planets in our solar system do not possess all of these characteristics. Additionally, the origin of life on Earth is still a topic of scientific investigation.

Who founded the earth is round?

The idea of a round Earth appears to have originated in Greek Philosophy. Aristotle provided the first evidence of a round Earth, noting that explorers traveling south saw southern constellations rise higher above the horizon and that Earth cast a round shadow on the moon. Eratosthenes used the angle of sunlight at different latitudes to estimate Earth's circumference with surprising accuracy.

Is earth shaped like a pear?

yes it is the world may look round but it is actually pear shaped

What materials make the planet earth?

coal, metal and gemstones are the main 3 things found in the Earth's crust.

Why is earth called the grand oasis?

Earth is sometimes called the "Grand Oasis" because it is one of the few planets in our solar system known to have liquid water on its surface, making it a haven for life as we know it. This abundance of water and life-supporting conditions makes Earth a precious and unique oasis in the vastness of space.

How many times smaller will the sun look on Uranus than Earth?

The sun will appear about 160 times smaller from Uranus compared to Earth due to the greater distance between Uranus and the sun. This is because Uranus is much further away from the sun than Earth is.

What are 3 reasons that Venus is called earths sister planet?

  1. Venus is similar in size and mass to Earth, making them roughly "sister planets" in terms of their physical characteristics.
  2. Both Venus and Earth are rocky planets with similar compositions and densities.
  3. They are relatively close to each other in the solar system, with Venus being the closest planet to Earth.

What planet is physically most similar to the earth?

Either Venus or Mars.

  • Venus is probably the closest match, in terms of size, mass, and density. It's atmosphere is very different, however. It's atmospheric pressure at the surface is almost 100 times that of earth, and it is made up almost completely of carbon dioxide. Temperatures are extremely hot and it has sulfuric acid rainfall and molten sulfur on the surface. Even unmanned probes don't last long on the surface due to the hellish conditions. It is one of two planets in the solar system without a satellite.
  • Mars is smaller but roughly the same density. it has a thinner atmosphere, but the temperatures are much closer to that on earth - similar to arctic and antarctic regions of the Earth. It also has a couple of moons. Although the environment is harsh, it is possible that humans may land astronauts there before the end of the century.

Does the earths tilt have anything to do with the seasons?

Yes, the Earth's tilt is the main reason for the seasons. As the Earth orbits around the Sun, its tilt causes different parts of the planet to receive varying amounts of sunlight throughout the year, resulting in the distinct seasons of spring, summer, autumn, and winter.

What is meant by the reference to the earth being an isolated planet?

When the earth is referred to as an isolated planet, it usually means that the earth is distinct from other celestial bodies in terms of its environment and characteristics. This isolation highlights the uniqueness of the earth in terms of its ability to support life and its position in the universe.
