Planetary Science

Oh, dude, that's a lunar eclipse! It's like when the moon is just chilling in the Earth's shadow, getting some shade from the sun. So, yeah, when Earth is like, "Hey moon, come over here and hang out in my shadow for a bit," that's a lunar eclipse.

The 3 criteria for an object to be a planet is: It must orbit the sun. The object must have enough gravity to be in a ellipticalshape. The object must be larger in mass than all of it surrounding objects. (ie. moons,meteors)

To qualify as a planet, a body has to be approximately spherical (achieving hydrostatic equilibrium under its own gravity), it has to orbit the sun and it has to have cleared its orbit of all other objects - so that at that distance from the sun, there are no other sizable bodies. Some dwarf planets, like pluto, fulfill the first two requirements, but not the last one, this is why they are deemed dwarf planets rather than planets.

The sky on earth is lit by the sun during the day. The sunlight hitting the atmosphere illuminates it. When the sun is below the horizon, after it sets, the part of the sky it illuminates gets smaller and smaller until its effect is no longer seen. This darkening time is called twilight until it is totally dark and becomes night.

Arcturus is a star located in the constellation of Boötes and is not known to have any planets orbiting around it. It is a red giant star that is relatively close to Earth in astronomical terms, at a distance of about 36.7 light-years. While exoplanets have been discovered around many other stars in our galaxy, none have been confirmed around Arcturus.

Rotation means rotating around in a full circle, or rotating around an object in a full circle. Rotation can also mean exchanging positions between people or objects. The meaning of the word can change slightly depending on the context of how it's used

Begotten means created by a means of reproduction. A son is begotten when his mother is impregnated by his father. It used to be believed that sunlight could cause creatures to be reproduced without any other assistance. We see an example of this in Act II Scene 2 of William Shakespeare's play Hamlet. Hamlet says, "For if the sun breed maggots in a dead dog, being a god kissing carrion", expressing the belief that the maggots were conceived by the action of sunlight on the dead dog, not by flies who laid their eggs on it. The maggots were definitely thought to be "sun-begotten".

It is called a revolution.

A "Star" can be anything from the beginning of a stars life (Protostar) up until it has died and only it's remnants remain (White dwarf, neutron star, black hole).

However, for this question, we will assume that a "star" is when it is fusing hydrogen into helium, which is what most stars we see, including the Sun are doing.

A protostar is the first stage in a stars life (See related question) whereas a "star" in this question is when there is enough pressure and thus temperature for the star to star fusing hydrogen into helium and it joins the main sequence - thus becoming a star (See related question)

Saturn is the sixth planet from the Sun in our solar system. It is located after Jupiter and before Uranus. Saturn is known for its distinctive rings, which are made up of ice, rock, and dust particles.

Johannes Kepler discovered that the Earth revolves/orbits the Sun in an ELLIPSE.

He also discovered that the Sun is NOT at the centre of the ellipse, but at one of the foci ; (plural of focus). The other focal point being 'blind'.

From this we have the definition, that as the Earth orbits the Sun , 'It sweeps equal arcs in equal times'.

As the Earth orbits, it speeds up and slows down. It is moving at its fastest when passing the Sun at it nearest point ( perigee) and slowest when at its furthest point ( apogee).

In the context of stellar evolution, a massive star's stage 4, also known as the red supergiant phase, differs from an average star's stage 4, which is the red giant phase, primarily in terms of mass and size. Massive stars have significantly higher mass compared to average stars, leading to more intense nuclear fusion reactions and the production of heavier elements in their cores. This results in a more rapid evolution and ultimately a more violent end stage, such as a supernova or even a black hole formation, compared to the relatively peaceful fate of an average star, which typically ends as a white dwarf.

No, not life as we know it. Saturn has no real surface, it's gas giant-- a fluid object, where the elements (mostly hydrogen) that compose it do not condense into a solid. There's no real separation between it's atmosphere and the planet itself, and the atmospheric gasses have been measured blowing at hundreds of miles per hour. Astronomers consider the actual planet Saturn to begin where the atmospheric pressure of the gasses reach one earth atmosphere.

It's believed deep inside the planet there's a small rocky core, with a surface that's extraordinarily dark, cold and windy. Also, the pressure would be very great.

100 pounds The gravity on the moon is approximalty 1/6 that of earth's gravity. *** To be more precise it's 102 pounds. The moon's gravity is about 17 percent that of earth's. Multiply any weight in earth by 0.17 to get its weight in the moon.

If a single planet formed around a single star, it is possible it's orbit could eventually assume an almost nearly perfect circularity. But planet formation is typically messy, as planetesimals collide and bind together. The formation of other planets induces further orbital perturbations.

After liposuction, it is crucial to avoid direct sun exposure for at least two to six weeks, depending on your surgeon’s specific advice. During the early recovery phase, your skin is sensitive and prone to complications like discoloration, scarring, or prolonged swelling if exposed to UV rays. Even after the initial healing, the treated areas and incisions require extra care to prevent hyperpigmentation or irritation.

When venturing outdoors, use a high-SPF sunscreen (30 or higher), wear protective clothing like long sleeves and a wide-brimmed hat, and try to stay in shaded areas. Avoid intense sun exposure during peak hours (10 AM–4 PM) and consult your doctor for personalized guidance on your recovery timeline

The planet with an orbit that intersects the orbit of the dwarf planet Pluto is Neptune. Neptune, the eighth and farthest known planet from the Sun in the Solar System, has an orbit that crosses Pluto's orbit due to its elliptical path around the Sun. This orbital relationship between Neptune and Pluto is one of the factors that led to Pluto's reclassification as a dwarf planet in 2006 by the International Astronomical Union.

Galaxies.

No. It takes 24 hours to bring the observed position of the sun (on average throughout the year) to the same place in the sky. Because the earth is going around the sun, each six months the sun is south at midday but pointing in an exactly opposite direction to the stars as it was 6 mths before. The rotation period is about 4 mins less than 24 hours.

Venus.

Edit: It's been said many times, but the distances between Earth and other planets vary as they move in their different orbits. The "outer planets" are so far away they never get as close as 100 million miles from Earth.

The most distant planet in our solar system is Neptune. It is the eighth and farthest known planet from the Sun, with an average distance of about 4.5 billion kilometers (2.8 billion miles) from the Sun. Neptune is a gas giant, similar in composition to Uranus, and it has a blue color due to the presence of methane in its atmosphere.
