What is the time taken for Hubble to complete one orbit around the earth?

the Hubble doesn't orbit the earth, it orbits the sun slowly fling farther and farther into space.

Which is the only planet having intelligent life?

The only one that humans are currently aware of is Earth. No other planet in our own solar system has intelligent life, and there is no conclusive evidence as of yet that intelligent life exists elsewhere.

How should you humans react to martians if they decide to visit planet earth?

As with any interaction with a new species, the key would be to approach with caution and open-mindedness, while prioritizing peaceful communication and understanding. It would be important to establish clear boundaries and rules of engagement to ensure the safety and well-being of both humans and Martians. Collaboration and cooperation could lead to mutual understanding and potentially beneficial outcomes for both parties.

Which planet takes about 365 days to orbit the sun?

The Earth takes about 365 days (1 year) to orbit the sun.

What are rift zones made of earth made of?

Rift zones are formed on Earth's surface due to tectonic plate movements where the plates are pulling apart. They are made of volcanic rocks, such as basalt, as magma rises to the surface through fractures in the crust. Rift zones are characterized by intense volcanic activity, earthquakes, and the creation of new crust.

How far do you need to be to not get burnt by the sun?

The distance you need to be from the sun to avoid getting burned depends on factors like the strength of the sun's radiation and the protection you have (e.g., sunscreen, clothing). On Earth, being about 93 million miles (150 million kilometers) away from the sun is a safe distance, but factors like the ozone layer and Earth's atmosphere play a crucial role in protecting us from the sun's harmful effects.

How big is the earth in the solar system?

Earth is the sixth-largest known object in our Solar system, preceded by Neptune and proceeded by Venus. Its mean radius is about 6,370 kilometers, its volume is about 1,083.21 x 109 km3, and its mass is about 5,973.6 Yg (Yottagrams, or 1021 kilograms).

Would human extinction solve the worlds pain?

yes because it will cause no more pollution and decrease the destruction of nature.

___________

No, that's silly. The earth is in fact feeling no pain. Humans are simply speeding up what are perfectly natural cycles on earth. The earth has gone through stages much more toxic than the present, and it will again. As we speed the cycles up, we are only hastening our own destruction, nothing more. The earth will go on following its natural cycles and will neither miss us nor be grateful for our passing.

What instrument did they use to find that the earth was round?

The ancient Greeks used simple observation and logic to determine that the Earth was round. They noticed the curvature of the Earth's shadow during a lunar eclipse, the different constellations visible at different latitudes, and the way ships disappeared hull-first over the horizon as they sailed away.

Which planet search technique is currently best suited to finding Earth like planets?

The transit method is currently best suited for finding Earth-like planets. This technique involves detecting the dip in a star's brightness as a planet passes in front of it, indicating the presence of a planet. It has been successful in identifying many exoplanets, including those that are similar in size and composition to Earth.

What is the percentage of coastal land on earth?

Approximately 40% of the world's population lives within 100 kilometers of a coast.

Does the Earth have more gravity than Jupiter?

Jupiter, the biggest planet in the solar system, has far more gravity than the Earth. Only the Sun has more gravity than Jupiter in our solar system.

What describes Earth's gravity?

Earth's gravity is a force that pulls objects towards its center. It gives weight to objects and keeps the Moon in orbit around the Earth. The strength of Earth's gravity decreases with distance from its center.

What two things are caused as the earth rotates on its axis?

The earth has only one rotational axis.

You can visualize it as a pencil stuck through the globe. It goes in at the north pole and comes out at the south pole.

What planet is most similar to Earth in mass and diameter?

Venus is most similar to Earth in terms of mass and diameter. Venus is almost the same size as Earth, with a diameter about 95% that of Earth, and its mass is about 81.5% of Earth's mass.

Is Earths rotation axis fixed in space?

No, Earth's rotation axis is not fixed in space. It undergoes a slow wobble known as precession, which takes about 26,000 years to complete one full cycle. This causes the orientation of Earth's axis to change over long periods of time.

What is the length of rotation and revolution periods of your planet?

The rotation periodof Earth is about23 hours and 56minutes.

The revolution period of Earth around the Sun is approximately 365.25 days.

How long had earth existed before any life appeared?

Earth is estimated to be around 4.5 billion years old. The earliest signs of life on Earth date back to approximately 3.5 billion years ago, suggesting there was around 1 billion years between Earth's formation and the emergence of life.

Does the earth have more mass than mars?

Yes. Earth is about 6.5 times larger than Mars and has more mass.

How do the earth contribute to the life cycle?

The Earth provides the essential components necessary for life to thrive, such as water, nutrients, and energy from the sun. It also acts as a habitat for a wide range of organisms, allowing for complex ecosystems to form and sustain life cycles through processes like photosynthesis, decomposition, and nutrient cycling. Additionally, the Earth's diverse environments offer different niches and conditions that support the adaptation and evolution of species over time.

Do earths rotation on its axis cause eclipse?

No, Earth's rotation on its axis does not cause eclipses. Solar eclipses occur when the Moon passes between the Earth and the Sun, blocking out the Sun's light. Lunar eclipses happen when the Earth passes between the Sun and the Moon, causing the Earth's shadow to fall on the Moon.

What has happened to the pattern of stars over the last thousands of years?

There have been no significant changes in the past thousand years. There have been many solar events though, such as a recent Total Solar Eclipse, where the the galaxy aligned. It happens around once ever 300,000 years or so.

You have to understand that the Universe has taken around 14 billion years to get to where it is today, changes in thousands of years are very minuscule and gradual.

Does earth have a brain?

Earth does not have a brain in the literal sense, as it is a non-living planet. However, the interconnected systems of the Earth, including the atmosphere, hydrosphere, biosphere, and geosphere, can be thought of as functioning in a complex and interconnected way, almost like a planetary-scale ecosystem.

How big is earths moons compared to other planets?

Earth's moon is relatively large compared to the moons of other planets in the solar system. It is the fifth-largest moon in the solar system. Compared to the size of Earth, the moon is about 1/6th the diameter of Earth.
