We do not know of any planets that have been destroyed by a black hole, but it probably has happened. Because of the vast distances in space and the fact that neither planets nor black holes emit light, both are hard to detect.

Dying in a hole can happen if you become trapped without anyone finding you in time, leading to dehydration, starvation, or asphyxiation if the hole lacks oxygen. It's important to always take safety measures when exploring holes or underground spaces to prevent such accidents.

The nearest star system to our solar system is Alpha Centauri, located about 4.37 light-years away. It consists of three stars, Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Proxima Centauri is the closest individual star to our solar system, at a distance of about 4.24 light-years.

The Sun-centered or heliocentric model of the solar system is called the Copernican model (after Copernicus) and more closely matches the modern astronomical notions. By contrast, the geocentric or Earth-centric model is often called the Ptolemaic.

Angaraka in English is Mars.

The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape

Because planets are rather small on astronomical scales - or at least, when compared to stars, and not luminous like stars, it is very hard to see them at great distances. NASA's Kepler spacecraft, which was launched to detect planets within habitable zones of stars, detected in 2011 a couple planets orbiting a star roughly 1000 light years distance. The planets, designated Kepler 20e and 20f, are part of an unusual solar system, and are roughly Earth-sized and 'rocky' but orbiting their host star within the distance of Mercury to our Sun, which would make them too hot for life.

The Moon is a natural satellite and the Sun is a star. The Moon is not a star. Neither the Moon nor the Sun are planets.

Yes, Venus has a thick atmosphere composed mainly of carbon dioxide with clouds of sulfuric acid. The atmosphere on Venus is extremely dense and creates a strong greenhouse effect, resulting in surface temperatures that can exceed 800 degrees Fahrenheit (427 degrees Celsius).

There are five planets in our solar system which are bigger than Venus;

1. Jupiter(has rings)

2. Saturn (special rings around it made with ice and rocks)

3. Uranus (has rings around it)

4. Neptune (also has rings around it)

5. The Earth (the twin sister)

MissFigglebot-

im doing a research project on venus

hope that helps

The orbit of a celestial body is its revolution about its primary. It can be explained in terms of the net result of gravitational forces acting upon the body, usually with emphasis upon the gravitational force exerted by its primary, which accelerates the body towards it, causing the object and its primary to revolve around a common center of gravity. The characteristics of the orbit are determined by the momentum of the body (kinetic energy or momentum being vector quantities, the vector's argument oriented approximately perpendicular to a line joining the body to its primary, or tangential to a circular orbit) and the strength of the force; the shape of the orbit is ideally elliptical with the primary occupying a position at one of the foci - remembering that a circle is a special ellipse with the foci superimposed. Note that with eccentric elliptical orbits, the axis of the ellipse itself will precess slowly over time, a phenomenon explained through relativistic effects. In the context of relativity, an orbit can be explained as a straight line (geodesic) through curved space shaped by gravitation - giving rise to one description of the properties of an orbit being the development (unfolding or mapping) in three dimensions of a four dimensional path through timespace.

They have several names. We can call them black holes, supermassive black holes, Singularities. The size of the black holes may vary and can be measured by their pull of gravity and their radiation. (Not that I want to go close for such a task)

I don't see any specific reason why you wouldn't be able to do that. Firing an arrow depends neither on the presence of air, nor on gravity. Both, however, will affect the movement of the arrow after you fire it.

A person who studies that category is called an astronomer.

Astronomers believe that the solar system is about 4.6 billion years old. This age is determined by studying the ages of rocks on Earth and meteorites from space that have been dated using radiometric dating techniques.

I can't tell you the exact time, but it would probably be somewhat quick.

The sun is made up litterally of flames and gas. All the black hole would have to do is pull the flames and gas into the mouth of the hole and the sun is gone. It seems to me that it would take a few minutes, depending on the size of the hole. If it is a small hole, made by a star about the size of our sun, it would take around three to five minutes. Maybe more.

hello im tess i think little stars are called anphebeansh

Black holes do not "suck in" large objects; black holes "suck in" only dust and plasma.

This is because by the time a large object gets anywhere near the event horizon of a black hole, the tidal forces caused by the gravity of the black hole has already pulverized whatever mass the object had. The gravitational force of a black hole's singularity is almost impossible to comprehend. It may not be strong enough to tear apart the nuclear forces of an atom. but it is certainly powerful enough to rip any two atoms apart, no matter how tight the chemical bonds might be.

The concept of the planet Nibiru, partly derived from interpolations of Babylonian and Sumerian mythology, and purportedly associated with an apocalyptic collision or near miss with Earth, is not supported by evidence, and is widely regarded as pseudoscientific and thus rejected by the astronomical community.

In our solar system, Uranus is described as having a cyan or aquamarine color attributed to atmospheric methane; Neptune a deeper blue color at least in part due again to methane. During the day, Earth's sky has a blue appearance to a ground-based observer (due to Rayleigh scattering.)

The planet with 25 known moons in the solar system is Saturn. These moons vary in size and composition, with some like Titan and Enceladus being of particular interest due to their potential for hosting conditions conducive to life.

uranus is the planet that have 27 satellites

Yes, there are limits for stars - limits to lower and upper mass, longevity, size, etc. Given the mass of the universe a limit for the number of extant stars would also exist. During stellar collapse at end of a star's life there are some well-studied limits answering to degeneracy pressure, like the Chandresekhar limit, the Oppenheimer-Volkoff limit, etc., which prevent further collapse until a certain mass limit is exceeded (perhaps the last limit being quark degeneracy pressure before further collapse into a black hole).

For further examination of a given limit, the limit in question would need to be identified.

The Doctor's home planet is Gallifrey from the TV show Doctor Who.

In our solar system, eight known planets revolve or orbit around the Sun (as do a lot of other objects, dwarf or minor planets, asteroids, comets, and so forth).
