Planetary Science

Terrestrial planets are close to the sun and include Mercury, Venus, Earth, and Mars. They are mostly composed of rock and metal. Gaseous planets are further from the sun and include Jupiter, Saturn, Uranus, and Neptune. They are mostly composed of gases like hydrogen and helium.

-- the object's weight

-- the atmospheric pressure on it

-- the temperature around it

-- the intensity of solar radiation on it

-- its distance from the nearest McDonald's

the force of gravity on the surface of the moon is about 1/6th the gravity on the surface of the earth so an object on the moon would weigh about 1/6th what it weighs on earth. The moon´s gravitational field is not strong enough to hold an atmosphere. As the atmosphere in part acts as a heatsink the temperature difference between day and night on the moon is far larger than on the earth.

The approximate length of the elliptical orbit is about 584 million miles. (about 583,955,000 miles)

This is about 939.8 million kilometers.

There are two ways to calculate the approximate value.

1) The approximate speed of the Earth in its orbit is about 66,600 mph. This is about 1,598,400 miles per days, for 365.25 days would be 583, 815, 600 miles.

2) The approximate radius of the Earth's orbit is 93 million miles. If the orbit were circular, the circumference would be (93 x 2 x pi) million miles, or about 584,335,740 miles.

Photosynthesis is the process that uses carbon dioxide and the sun's radiant energy to produce chemical energy in the form of glucose. This process occurs in the chloroplasts of plant cells and involves the conversion of light energy into chemical energy.

No, if the sun were replaced by a star with twice the mass, Earth's orbit would likely change. The gravitational force between the Earth and the new star would be stronger, causing the Earth to orbit closer to the star and potentially leading to a different orbital path.

Its the sun. The sun is approximately 1, 390, 000 km in diameter while the moon only 3, 475 km. plus the sun is the biggest star in our solar system. oh yeah woooooooooooooooooooooooooooooooooooooooooooooohhhhhhhhhhhhhh

The planet that orbits the sun at a speed of approximately 110,000 kph is Earth.

Gravity is the force that pulled all the dust and gas together to form the sun. The gravitational attraction between particles caused them to clump together, leading to the formation of the sun and the solar system.

The average temperature on Saturn is around -288 degrees Fahrenheit (-178 degrees Celsius). This extreme cold is due to the planet's distance from the Sun and its thick atmosphere, which traps heat from escaping into space.

Three types of bodies in the solar system besides dwarf planets, asteroids, and planets are comets, moons, and meteoroids. Comets are icy bodies that release gas and dust as they orbit the Sun, moons are natural satellites that orbit planets or asteroids, and meteoroids are small rocky or metallic bodies that travel through space.

Jovian planets can also be called gas giants. They are Jupiter, Saturn, Neptune and Uranus. They are mostly made up of gas, but they have a rocky core, (somewhere!). They are said to lack a solid surface, But they actually don't really have a surface at all! The gases that they're made up from get thinner and thinner as you get closer to the core.

This would happen, space junk could collide with asteroids, but most space junk is close to the earth, away from the main asteroid belt. It would be more likely to collide with meteroids and other bits of space junk.

Taking into account that the planet Mars orbits our Sun in about 687 days, while the Earth does the same in about 365 days, it comes down to simple math:

365 * 12 / 687 = 6,38 years.

First, the Sun cannot "burn out". Even if the hydrogen fusion that powers the Sun were to stop, the mass of the Sun and its slow collapse under the forces of gravity would keep it shining much as it does now for thousands of years.

But if the Sun were to magically "turn off", the surface of the oceans would begin to freeze over in about 2 days, as surface heat would continue to be radiated off into space. (Have you ever wondered why clear winter nights are so much colder than cloudy winter nights? Radiation.) The deep oceans would freeze more slowly, and might never freeze completely; the ice would provide insulation, and the volcanic heat from deep sea vents might provide enough heat to keep the oceans from freezing completely for millions of years.

New material was likely added to planets in a young solar system through processes like accretion and impacts from asteroids and comets. These small bodies collided with the growing planets, contributing to their mass and composition. Over time, these collisions helped shape the planets and their eventual characteristics.

The force of gravity between the planets and the sun keeps them in orbit and prevents them from flying out of the solar system. The sun's gravitational pull keeps the planets in stable orbits around it.

The Earth's surface is unique among the inner planets due to its abundance of liquid water, which allows for the presence of life. Earth also has a diverse range of landforms such as mountains, oceans, and continents, along with a thick atmosphere that supports weather systems. These features differentiate Earth from the other inner planets like Mercury, Venus, and Mars, which lack significant surface water and have different geological characteristics.

it makes it easier to communicate long distances, before internet, air travel and radio it would take weeks, maybe months, to get a message from, for example, England to Australia because the earth is so huge. With internet you can talk face to face with people all over the world instantly. This acceleration of communication makes the world 'smaller'.

15 million Kelvin is an important temperature in the context of nuclear fusion because it is the temperature required to initiate the fusion reaction in stars like our sun. At this temperature, the hydrogen nuclei have enough kinetic energy to overcome their mutual repulsion and fuse together to form helium, releasing a tremendous amount of energy in the process. Achieving such high temperatures on Earth is a major challenge for potential fusion power plants.

Well it depends. You usually can see the planets closest to earth like Mercury, Venus and Mars and you can see Saturn's rings. But most likely u will not see anything more than those that I named. It doesn't really depend on the month. At least not all the time.

There are four Terrestrial planets. The Terrestrial planets in order according to radius size are:

1. Mercury (0.383 km)

2. Mars (0.533 km)

3. Venus (0.950 km)

4. Earth (1.000 km)

It is estimated that eridanus is 52 million light-years away from earth. Eridanus was named after the greek goddess Eridalica. the word eridanus means envious one.

the brightest star in the constellation is achernar, alltogether their are 21 stars in this constellation.

the legend of eridanus is that: one day while while caring to her garden the young Eridalica fell asleep and dreamt of soaring thourgh the sky.Only it wasn't a dream Eridalica saw her dead body on the garden of her roses and saw she had been murdered there was a dagger in her back and reconized it to be her her guard's Ferrnipoli. Eridalica was angered and swore revenge on Ferrnipoli, and she went into the sky to gather stars to fight with her along her side. as she and the stars thrust him upward into the sky, creating the constellation eridanus. still to this day, Ferrnipoli

begs Eridalica to set him free.

Yes, there is a difference in blood pressure between the major arteries of the neck and the legs. Blood pressure is normally higher in the major arteries of the neck (such as the carotid arteries) compared to those in the legs (such as the femoral arteries) due to differences in distance from the heart and the resistance of blood vessels in those areas.
