What is a pulsar?

A supernova leaves behind a tiny object termed a neutron star, which is far smaller than the Earth. It is the core of the star that exploded. The protons and electrons of its atoms have been squashed together by the force of the supernova, and they form the atomic particles known as neutrons. A n (MORE)

What is the closest the earth gets to the sun?

91,405,436 at perigee, which is the point that the earth is closest to the sun. Note: . The term would be perihelion for a body orbiting a sun. It is the same concept as perigee. The moon, orbiting around the earth, has an apogee and perigee.

What is the closest planet to the earth?

Every planet revolves around the sun, each one taking a different amount of time to complete one revolution. So the distance between Earth and any other planet changes over a wide range, depending on whether we're both on the same side of the sun or on opposite sides. At any given time, the planet (MORE)

What planet gets closest to the earth?

Which planet's temperature is closest to that of Earth?

None. All planets have very different temperatures at the surface. Mercury's Maximum Temperature 465°C (870°F) Mercury's Minimum Temperature -184°C (-300°F) Venus' Average Temperature 449°C (850°F) Earth's Average Temperature 7.2°C (45°F) Mars's Maximum Tempera (MORE)

Which star is closest to planet Earth?

The sun (also known as Sol), which is also a star, is the closest to Earth. Other than the sun, the closest star is called Proxima Centauri, and it is about four and a half light years away, or about 32 trillion miles away. That's the closest.

What is pulsars?

A Pulsar or Neutron Star is the remnants of a collapsed Super Giant, created during a Super Nova. The neutrons are so densely packed that they warp the gravity around the dying star so that any radiation (radio waves) emitted from it doesn't always shine at us. Due to this warping the star becomes m (MORE)

What layer of the atmosphere is closest to earth?

The Troposphere is nearest and extends from the surface of the earth to approximately 10 thousand metres above the surface. This explains why the air is described as being 'thin' when at the top of some of the highest mountains of the World. Hope this helps.

When is Ceres closest to earth?

Its orbital period is 4.60 years; since that is not an exactmultiple of the Earth year, the closest approach is not at the samedate every year. You can check astronomical sites for "oppositionof Ceres"; the closest approach is usually close to the opposition.For example, in 2016, Ceres was in opposi (MORE)

What is the closest dwarf planet to earth?

Ceres. It's the largest object in the asteroid belt, which lies between Mars and Jupiter, and the only asteroid massive enough to become approximately spherical in shape - one of the requirements to achieve dwarf planet status. The other 4 confirmed dwarf planets, including Pluto, are all much furth (MORE)

When are Mars and Earth the closest?

Much has been made of the fact that the August 27th encounter with Mars is the closest in some 60,000 years. Neanderthals were the last to observe Mars so favorably placed. This is true. It's also a bit of hype. Mars and Earth have been almost this close many times in recent history. Some examples: (MORE)

What effect do neutron stars and pulsars have on Earth?

Hardly any - they are very far away. However, a supernova (which would come before a neutron star) could have catastrophic effects on Earth, if it were to happen in our neighborhood (up to a few thousand light years!).

Are stars the closest to earth?

Those that are closest are the closest stars to earth. The champion closest star ... the closest of all of them ... is the sun. Coming in at a distant second place, the next closest star is 278 thousand times farther from earth than the sun is.

Is Jupiter the closest planet to Earth?

No. Generally speaking, Venus is the closest planet to Earth. The actual distance that Venus is from Earth varies, depending on where it is during its orbit around the sun relative to that of Earth. When Venus and Earth are on the same side of the sun, they are 38.2x10 6 km apart; when they are on (MORE)

What is the name of the galaxy closest to the Earth?

The Earth is inside the Milky Way Galaxy. The closest other known galaxies are the two "clouds of Magellan", which are small galaxies that orbit the Milky way. The closest other large galaxy, about the size of the Milky Way, is the Andromeda Galaxy. Andromeda is the nearest galaxy to Earth. Ans (MORE)

What is the closest star to Earth is?

What is the closest brown dwarf to earth?

Difficult to know for sure. Brown dwarf stars are small and dim, and it's possible that there is one relatively close by that we've never noticed. The nearest known brown dwarf star is Epsilon Indi Bb, one of two brown dwarf stars orbiting the star Epsilon Indi. It would not be detectable at all (MORE)

What planet with the closest orbit to earth?

That would probably be Venus, though there is room for debate there. Answer: Mars and Venus are our closest neighbouring planets. At its closest, Venus is 41,840,000 km away. The minimum distance to Mars is 56,000,000 km. Venus is more than 10 million kilometers closer than Mars.

What would happen if Earth was a pulsar?

Earth is a planet, not a star; it can never be a pulsar. For an excellent description of what life might be like on the surface of a pulsar, read the boon "Dragon's Egg" by Dr. Robert Forward.

What is a a Pulsars?

Pulsars are neutron stars that are formed when a large star burns up its fuel and collapses on itself. The process happens when fuel is exhausted so that the star cannot produce heat energy which causes it to expand. Gravity causes it to collapse and then when it is suddenly so compacted the heat be (MORE)

What city on earth is closest to the moon?
