Planetary Science

The Earths orbit is fairly un-eccentric when compared to the other planets, with only Neptune and Venus having more regular (less eccentric) orbits. The eccentricity of earths orbit is 0.0167, the closest to this is Neptune's, with a value of 0.00859

The size of a planet does not directly impact the eccentricity of its orbit. The eccentricity of a planet's orbit is primarily influenced by gravitational forces from other nearby celestial bodies and the planet's initial conditions during its formation. However, the mass of a planet can affect its gravitational interaction with other objects in its vicinity, which in turn may influence its orbit eccentricity.

No, the sun does not orbit around stationary planets. In our solar system, planets orbit around the sun due to its gravitational pull. This is known as heliocentrism, which describes the sun as being at the center of our solar system.

The last time the planets aligned in a straight line while revolving around the sun was on March 20, 1345. This phenomenon, known as a planetary alignment, occurs when several planets appear in a line relative to the sun from the perspective of Earth.

Gravity works as a magnet to hold us to the ground.

The next predicted total solar eclipse after August 11, 1999, occurred on December 4, 2002, but it wasn't visible from a wide area. However, a more significant total solar eclipse visible over a larger region occurred on March 29, 2006.

Earth is the largest terrestrial (all rock) planet in the solar system (check the Answers.com question "How BIG is Venus to earth?" The gas giant planets (like Jupiter, Uranus, and Saturn) do have a rocky surface below the vapor cloud that surrounds them. Jupiter would have the largest rocky surface if all the gas burned away.

These are the four outer gas giant planets; Jupiter, Saturn, Uranus and Neptune. They are all much larger than the inner planets, they all have a similar composition (gaseous atmospheres, mainly of Hydrogen and Helium) and they each have many moons and a ring system. None of the inner planets have a ring system and there are only three moons in total for the four inner planets (one for Earth and two in orbit around Mars).

Saturn was known from antiquity. Uranus was discovered in 1781 by William Herschel, who cataloged many interesting objects in our sky. In 1846 Neptune was discovered by Urbain Le Verrier, who predicted its position, and Johann Galle who made the initial observation.

Yes, light is affected by Earth's gravitational pull. According to the theory of general relativity, light bends when passing through regions with strong gravitational fields, such as around massive objects like Earth. This effect is known as gravitational lensing.

Triton is the largest moon of the planet Neptune.

It was discovered by William Lassell on October 10, 1846.

It is the only large moon in the Solar System with a retrograde orbit.

It is the seventh largest moon in the Solar System

It is geologically active as it's surface is young and has relatively few impact craters.

Its surface covered with cold liquid lava, ice and water.

Uranus was the bluish-green gas planet discovered in 1781 by astronomer William Herschel. Its distinctive color is due to methane gas in its atmosphere.

Mercury, 57,909,175,000mVenus, 108,208,930,000mEarth, 149,597,890,000mMars, 227,936,640,000mJupiter, 778,412,010,000mSaturn, 1,426,725,400,000mUranus, 2,870,972,200,000mNeptune, 4,498,252,900,000m

The four inner, rocky planets are also known as the terrestrial planets. These are; Mercury, Venus, Earth and Mars. The four outer gas giant planets are Jupiter, Saturn, Uranus and Neptune. The inner planets are smaller and have a higher average density. The outer planets are much larger, but have no real surface - just atmosphere that gets thicker as you travel inwards. The outer planets all have a ring system (the inner planets dont) while the outer planets have captured a lot more natural satellites or moons than the inner planets.

If Earth rotated faster, days would be shorter because the planet would complete a full rotation in less time. This would result in shorter daylight hours and potentially disrupt ecosystems, weather patterns, and daily routines.

Yes, the orbits of inner planets in our solar system are relatively closely spaced compared to the outer planets. This is due to the gravitational influence of the massive gas giants further out, which helps maintain the spacing of the inner planets.

Venus, Earth and Pluto.

They can appear in the middle of the night. Shooting stars can pass at anytime, they don't happen only at that time. You are actually more likely to see meteors in the pre-dawn hours of the morning, with 6 AM usually being the peak time.

Venus.

Mercury = 66 days

Mars = 1.86 years.

There are many different possibilities depending among other things on the size, composition and heat of the objects, and their velocity relative to each other when they collide. Two possibilities: they might just bump each other and go on their way with very little damage, or they might smash each other completely to bits.

The five most visible planets (Mercury, Venus, Mars, Jupiter, Saturn) can often be seen at different times of the year depending on their positions in their orbits. However, there are times when some or all of these planets are visible together in the predawn or post sunset sky. Consulting a stargazing app or website can help you identify when and where to look for them in the night sky.

Galileo Galilei concluded that all planets must orbit around the sun after observing that Venus exhibited phases similar to the moon, which could only be explained if Venus orbited the sun.

The temperature 2 meters under the Earth's surface varies depending on location, but generally, it can be estimated to increase by about 25-30 degrees Fahrenheit for every kilometer in depth due to the geothermal gradient. Therefore, it would be slightly warmer than the surface temperature.

it depends if you are religious or not but i believe it was the un-evolved humans and other prehistoric creatures including dinosaurs and other very ancient animals that are mostly all extinct now.
