Why is planet that can sustain life called a goldilocks planet?
Because Goldilocks, when she visited the three bears house, didn't like the porridge that was too hot or too cold. Instead, she liked the porridge that was just so.
Well it is the same thing with planets. Life as we know it can't survive on a planet too close to the sun because it will be too hot and a planet too far from the sun will be too cold for life. In other words, to sustain life, the planet needs to be in "the Goldilocks zone" that is "just right" to support life.
Why does the Earth rotate in single direction?
Once an object, any object, such as the Earth, is set in motion to rotate in a particular direction, it will always continue to rotate in that direction. For the Earth to rotate in another direction would take an enormous, cataclysmic force that would have to be created by a gigantic object colliding with it, or at least coming very close to it.
Why earth is a suitable planet for living not the other planets in solar system?
Because water, oxygen is only on the earth these two things are very important for living.
Second answer
This is because earth is in what is known as the "Goldilocks zone." If we were any closer to the sun, then all of the seas would boil. If we were further away, the seas world freeze. We are positioned where our world is just warm and wet enough to produce life. This does not make earth special, though. There have been numerous planets found in other solar systems that are in the Goldilocks zone.
Why is the earth 23 degrees tilted?
The Earth is tilted at an angle of approximately 23.5 degrees relative to its orbit around the sun. This tilt, known as obliquity, is believed to have been caused by collisions with other celestial bodies early in its formation. It is this tilt that gives rise to the Earth's seasons.
Is there any life on planets exepet earth?
As of now, there is no definitive evidence of life on any other planet in our solar system or beyond. However, scientists are actively searching for signs of life on exoplanets within the habitable zone of their stars, where conditions may be conducive to the existence of life.
Will life exist on earth without CO2?
CO2 is required to support all plant life. Plant life creates Oxygen, and most life forms cannot survive without Oxygen. Therefore there is a mutually dependent relationship between the 2. No CO2 leads to no O2, and all life on Earth dies. So, no.
Are all planets made up of solid like earth?
Unfortunately, the definition of a planet does not include it's composition.
So Mercury, Venus, Earth and Mars are classed as terrestrial planets - made up of rock, whereas Jupiter and Saturn's are classed as Gas Giants - not surprisingly, as they are comprised of mainly gases - hydrogen and helium, whereas Uranus and Neptune are classed as ice giants - yep, you've guessed it.
..and that is the planets in our Solar System, outside, most exoplanets are gas giants.
So all planets are not terrestrial.
How much fuel is needed to travel from earth to Jupiter?
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.
Why does Earth have a magnetic field and Venus does not?
Earth has a magnetic field because it has a liquid outer core made of iron and nickel that generates a dynamo effect. Venus, on the other hand, lacks a magnetic field because its core is believed to be mostly solid and doesn't have the same composition to generate a magnetic field.
How far away from earth is zeta reticuli?
The Zeta Reticuli binary star system is located 39.17 light-years, or 230,265,762,450,700.25 miles (That's 230 trillion miles) away from the Earth. At that distance it would take a Saturn V rocket 1,072,165.5 years to travel there.
Why is the sun brighter than usual?
The Sun may seem brighter than usual as the Earth's ozone layer has degraded ~80% since the mid 1970's due to the prodution and use of fossil fuels. The Ozone layer is the part of the atmosphere which absorbs the vast majority of solar radiation, and thus a detriment of 80% of it's original composition will impose an inverse effect on it's ability to absorb the sun's radiation. Human beings, and all of the 30 million species on the planet were evolutiuonarily designed for an ozone layer about 5 times the strength ours is now, as we evolved prior to the environmental stresses indirectly imposed by over use of fossil fuels. This can be characterized medically by the increase in melanoma and skin-diseases since 1974 (Initial melanoma incidence 1/1800 in 1970, melanoma incidence 1/50 nowadays, 1/20 by 2025). We can use sunscreen to mitigate the risk of getting these diseases, though the other 30 million species on the planet, which are typically outside and exposed to the sun, will likely die off or mutate in time and will thus offset the ecosphere mechanics to an endgame state, such that our pedestal at the top of the chain will not be so supported.
The tradeoff of the use of fossil fuel benefits (cheap transportation, heating, air conditioning) happens to offset the entire sustainability of the earth's ecology, a very sad thing. On the other hand, air conditioners are very pleasant on a hot day.
Can you eliminate microorganisms on earth?
It is not feasible to completely eliminate all microorganisms on Earth without causing significant ecological imbalances. Additionally, microorganisms play vital roles in nutrient recycling, food production, and disease control. It is more practical to manage and control harmful microorganisms through strategies such as hygiene practices, vaccinations, and antimicrobial treatments.
How much of the planet Earth is made up of water?
Surprisingly little. Water covers a little under three-quarters of Earth's surface, but it's almost all on (or just below) the surface, so a relatively tiny fraction of Earth is water.
What planets appear within 50 degrees of the Sun from Earth?
The five planets that can appear within 50 degrees of the Sun from Earth are Mercury, Venus, Mars, Jupiter, and Saturn. Uranus and Neptune are typically too far from the Sun to appear within this range due to their positions in the outer solar system.
What logo has a fox round the earth?
The logo you are referring to belongs to the Firefox web browser, which features a fox circling the globe. The fox in the logo is known as the Firefox mascot, and it symbolizes speed, agility, and global reach.
Which is the force that pulls objects toward centre of the earth?
The force that pulls objects toward the center of the Earth is called gravity. Gravity is a fundamental force of nature that attracts objects with mass toward each other. It is responsible for keeping the planets in orbit around the Sun and objects on Earth's surface from floating off into space.
What is the world's most Eco efficient living creature?
The leafcutter ant is considered one of the most eco-efficient living creatures. They live in complex colonies where each ant has a specific role that contributes to the overall efficiency of the colony. They are excellent at recycling and have a minimal impact on their environment.
How many habitants live on earth?
As of 2021, the estimated global population is around 7.9 billion people. This number is constantly changing due to factors such as births, deaths, and migration.

Where and which is the natural biggest holes in the earth?
The world's biggest hole - Mirny Diamond Mine is located in Russia
The giant hole is actually a diamond mine in Eastern Siberia near the town of Mirna. It is 525 meters deep and 1.25 km in diameter.
Why earth is often called a blue planet?
The Earth is mainly covered in water, even more than land. when seen from space, Earth is mostly blue because of the oceans, ans so is called the blue planet. this is also from the fact that we are the only planet in the solar system that can support life, because we have drinking water.
Earth's axis has a tilt of 23.5 degrees; this is what causes seasons. 0 degrees: practically no seasons (there would be minor changes due to a varying distance from the Sun). 45 degrees: seasons would be much more pronounced.
How long do water exist on earth?
Water has been present on Earth for billions of years, since the planet's formation. The water cycle continuously recycles and redistributes water on Earth, ensuring its existence. As long as Earth maintains the conditions needed to support life, water will continue to be a fundamental element on our planet.
What is the most poisonous invertebrate on planet earth?
The most poisonous invertebrate known on planet earth is the box jellyfish, or sea wasp.
Who was the first singer who lived on planet earth?
Not absolutely sure about the very first singer but I can tell you some things that I know according to my literature knowledge. So, in ancient times Greece people used to go to theaters to see plays by Sophocles, Aeschylus (the most famous and the best authors then) . It's a fact that this was the time when drama appeared. While the actors were performing there weren't only actions. There was a choir who used to sing in some parts of the play. I'm talking about the times 456/455 BC. It's logical that these may be the first singers. Hope this will help
