Why can all on the earth not see the sun at the same time?
First of all the earth is on an axis that slowly spins everyday. making it impossible for both sides to have the sun on all of it everyday. Second is that we rotate around the sun so only one part can have the sun on it. The way sunsets and sunrises come up are because the earth is turning making us see part of the sun but not all of it. That is also why we have seasons and why there are different time zones. It is because the earth is always turning. Take your hand for instance if you tilt it to the side and go outside, only one part of your hand will have sun on it. If you turn your hand some than a different part of your hand has sun that is kind of how the earth works.
What are the physical properties of the sun?
The Sun is a ball of hot plasma, primarily composed of hydrogen and helium. It has a diameter of about 1.4 million kilometers and a surface temperature of about 5,500 degrees Celsius. The Sun emits light, heat, and other forms of radiation.
Sunspots are temporary disturbances in the sun's?
Sunspots are the temporary dark spots on the surface of the sun, specifically the photosphere. Sunspots can get as big as 50,000 km long. Sunspots can interrupt terrestrial magnetism.
How many suns can fit inside vv cephei?
Around 1.15 billion suns could fit inside VV Cephei, which is one of the largest known stars in the universe. Its diameter is estimated to be about 1,650 times larger than the Sun's.
Why does the sun appear at east to west?
The sun appears to move from east to west in the sky due to the rotation of the Earth on its axis from west to east. This rotation causes the sun to rise in the east and set in the west as the Earth moves in its orbit around the sun.
How close do fire bursts from the sun get to earth?
Solar flares and coronal mass ejections, which are fire bursts from the Sun, can erupt up to millions of kilometers in space, but usually do not get close enough to directly impact Earth. However, if such events are strong enough, they can affect our planet by disrupting satellites, power grids, and communication systems.
The solar system consists of the sun and all the celestial objects that orbit around it, such as planets, moons, asteroids, and comets. It includes eight planets, with Earth being the third from the sun, and is located within the Milky Way galaxy.
How long will solar power last for?
Solar energy will be available for the taking on Earth until the sun itself begins to run low
on fuel, and swells up to become a huge, cool giant ... a few billion years.
The human race on Earth will be gone long before that, so there's nothing to worry about.
The Sun appears stationary from the perspective of Earth due to its immense distance and the Earth's orbit around it. However, the Sun is actually in motion, revolving around the center of the Milky Way galaxy at about 483,000 miles per hour.
A scorching sun is an intense and blisteringly hot sun that radiates extreme heat. It can cause discomfort, sunburn, and dehydration if proper precautions are not taken such as wearing sunscreen and staying hydrated.
Where will the sun reach its highest point?
The sun reaches its highest point in the sky at solar noon, which is when it is directly overhead an observer at the Tropic of Cancer or the Tropic of Capricorn, depending on the time of year. This position is known as the sun's highest altitude or culmination.
A pyranometer is a device used to measure solar radiation. It measures the total solar radiation received from the sun at a specific location in watts per square meter. Pyranometers are commonly used in meteorology, climatology, solar energy research, and agriculture.
No, the sun is not breaking apart. It is a stable star that is undergoing nuclear fusion in its core, converting hydrogen into helium and releasing energy in the process. The sun is expected to remain stable for billions of years to come.
Will the sun die after 500 billion years?
Yes, eventually, the sun will exhaust its nuclear fuel and expand into a red giant, consuming Mercury and Venus in the process. After this, it will eventually shed its outer layers, forming a planetary nebula, and the remaining core will cool and shrink into a white dwarf. This process is estimated to occur in about 5 billion years.
What is the sun is the sun big or small?
The sun is a medium-sized star compared to others in the universe. It is classified as a G-type main-sequence star, or more commonly known as a yellow dwarf star. Its size appears large to us because it is the closest star to Earth.
How do you know the sun is made of fire?
The sun is not made of fire, but rather composed of hot plasma mainly made up of hydrogen and helium. It undergoes nuclear fusion at its core, where intense heat and pressure create the extreme temperatures and energy we observe as sunlight.
Who discovered that the orbits in which the planets move around the Sun are elliptical?
Johannes Kepler discovered that the orbits of planets around the Sun are elliptical in shape. Kepler's work on planetary motion led to his three laws of planetary motion, which revolutionized our understanding of the solar system.
Why is the sun brighter than usual?
The Sun may seem brighter than usual as the Earth's ozone layer has degraded ~80% since the mid 1970's due to the prodution and use of fossil fuels. The Ozone layer is the part of the atmosphere which absorbs the vast majority of solar radiation, and thus a detriment of 80% of it's original composition will impose an inverse effect on it's ability to absorb the sun's radiation. Human beings, and all of the 30 million species on the planet were evolutiuonarily designed for an ozone layer about 5 times the strength ours is now, as we evolved prior to the environmental stresses indirectly imposed by over use of fossil fuels. This can be characterized medically by the increase in melanoma and skin-diseases since 1974 (Initial melanoma incidence 1/1800 in 1970, melanoma incidence 1/50 nowadays, 1/20 by 2025). We can use sunscreen to mitigate the risk of getting these diseases, though the other 30 million species on the planet, which are typically outside and exposed to the sun, will likely die off or mutate in time and will thus offset the ecosphere mechanics to an endgame state, such that our pedestal at the top of the chain will not be so supported.
The tradeoff of the use of fossil fuel benefits (cheap transportation, heating, air conditioning) happens to offset the entire sustainability of the earth's ecology, a very sad thing. On the other hand, air conditioners are very pleasant on a hot day.
Is the sun illuminating the moon at all times?
No, the sun does not illuminate the same side of the moon all the time. The moon goes through different phases as it orbits the Earth, so the amount of illumination it receives from the sun changes throughout its cycle.
What happens when a solar flare hits earth?
The last answer 'the earth is goin to explode because dats something coming from the sun fast' is absolutely rubbish! The solar flare is harmless to Earth because Earth has its own magnetic field so that the solar flare will do very little harm to Earth. After all, the Earth didn't explode on 24/1/2012, when the flare pass earth. The solar flare passing Earth's atmosphere at the two poles (where the magnetic field is close to ground) at high speed creates polar light. It also cause some disturbance to electrical transmission through space and aviation. Astronauts out of Earth's magnetic field, however, have to take measures to prevent direct exposure to the flare.
But even there isn't a magnetic field for Earth, like Mars, matter will only evaporate into space, the planet will not explode.
What happens on earth as a result of a solar flare?
Solar flares can release a burst of energy in the form of electromagnetic radiation, which can cause disruptions to satellite communications, power grids, and navigation systems on Earth. Additionally, they can also result in beautiful auroras at the poles.
What is the 6 closest planet to the sun?
1. mercury 2. venes 3. earth 4. mars 5. jupiter 6. saturn those are the 6 closest planets to the sun
How long does it take the sun to complete one orbit around the galactic nucleus?
Astronomers tell us between 225,000 and 250,000 years.
Will the sun come out from the west?
No, the sun rises in the east and sets in the west due to Earth's rotation. It is not possible for the sun to change its course in this way.
