Biggest volcano in the solar system?

It was thought to be mars's Olympus Mons that held title for the largest volcano in the solar system however new evidence points that it might actually be on earth. The volcano is called Tamu Massif and sits in the Pacific Ocean it is said to be a whopping 400 miles wide and the magma chamber extends over 1,200 miles into the earth!

How discovered nanomites?

The history of nanotechnology traces the development of the concepts and experimental work falling under the broad category of nanotechnology. Although nanotechnology is a relatively recent development in scientific research, the development of its central concepts happened over a longer period of time. The emergence of nanotechnology in the 1980s was caused by the convergence of experimental advances such as the invention of the scanning tunneling microscope in 1981 and the discovery of fullerenes in 1985, with the elucidation and popularization of a conceptual framework for the goals of nanotechnology beginning with the 1986 publication of the book Engines of Creation. The field was subject to growing public awareness and controversy in the early 2000s, with prominent debates about both its potential implications as well as the feasibility of the applications envisioned by advocates of molecular nanotechnology, and with governments moving to promote and fund research into nanotechnology. The early 2000s also saw the beginnings of commercial applications of nanotechnology, although these were limited to bulk applications of nanomaterials rather than the transformative applications envisioned by the field.

When was the last time that Palm Sunday and April Fools' Day were on the same day?

Since 1875, Palm Sunday has been on April 1 in the years 1917, 1928, 2007 and 2012. It will be on April 1 again in 2091.

What planet in our solar system is morning star?

The "morning star" is a fascinating celestial phenomenon that has intrigued humans for centuries. In our solar system, the morning star refers to the planet Venus. However, it's important to note that Venus is not exclusively a morning star—it can also be seen as an evening star at times.

Venus, our neighboring planet, has captured the imagination of stargazers and astronomers alike due to its radiant appearance in the early hours before sunrise. This phenomenon occurs because of Venus' relative proximity to Earth and its orbital position around the Sun.

Like all planets in our solar system, including Earth, Venus revolves around the Sun. However, due to its orbit being closer to the Sun than ours, there are instances when Venus appears on one side or another of Earth's sky compared to where we are in our orbit.

When Venus lies on the same side of its orbit as us (between us and the Sun), it becomes visible just before dawn—hence earning it the title of "morning star." At this time, as sunlight reflects off Venus' dense atmosphere back towards Earth like a dazzling mirror, it outshines all other celestial bodies except for our Moon.

The brilliance and beauty displayed by Venus during these pre-dawn moments captivate many observers. Its presence adds an ethereal sparkle amidst twilight's soft hues; simultaneously providing an awe-inspiring backdrop while heralding imminent daylight.

However enchanting this sight may be from afar though, if one were able to visit Venus up close they would find themselves confronted with extreme conditions unsuitable for human habitation. Temperatures soar above 900 degrees Fahrenheit (475 degrees Celsius), comparable only to Mercury despite being significantly farther from our scorching sun.

Furthermore, thick clouds composed mainly of sulfuric acid enshroud its atmosphere making visibility challenging and atmospheric pressure nearly 100 times greater than that found on Earth—a crushing weight too immense for any life form known today.

In conclusion, Venus takes on the role of "morning star" in our solar system, offering us a celestial spectacle as it graces our sky before sunrise. Its radiance serves as a testament to the wonders and mysteries that lie beyond Earth's boundaries. So next time you're up early enough to witness this breathtaking sight, take a moment to appreciate the beauty and marvel at the science behind our neighboring planet—the morning star, Venus.

Why do the planets revolve around the sun instead of the sun revolving around the planets?

The main reason is that the Sun is far more massive than the planets so if you look at the force of gravity, which operates between the Sun and each planet separately, that force is enough to hold the planet in its orbit round the Sun without the Sun having to move very much at all.

The Sun is 330,000 times more massive than the Earth, so the force of gravity between them produces 330,000 times more acceleration on the Earth than it does on the Sun. That is why the Sun stays in one place.

Can planets fall?

Yes. In our solar system the planets orbit the sun. The process of orbiting is a process of falling towards the sun, but their sideways speed is such that they continually miss (and thus end up going round) the Sun.

So, yes planets can and do fall but they do not fall intothe sun. Thus from our viewpoint they do not appear to be falling.

What gasses are in the solar systems atmosphere?

Hydroyen,helium,Iron,carbon moxide,water,sodim and calcim

What are some advantages and limitations of solar system models?

A solar system allows a star to exist in a stable condition by taking most of the angular momentum that arose when the star condensed from a random cloud of gas. Without a solar system the average star would spin much too fast and start to fly apart, forming another solar system.

Is earth a system?

Earth comprises of various components. It acts as a system.

What is used to measure distance between objects in the solar system?

The unit used is the astronomical unit, defined as the semimajor axis (mean radius) of the Earth's orbit.

The distances are scaled according to Kepler's laws of planetary motion. The fundamental distance is the distance to Venus on a close approach, which was measured accurately by triangulation from two points on the Earth's surface during a transit.

Where are most asteroids in the solar system located and why?

Most of the asteroids in our Solar system are located between the orbits of Mars and Jupiter. It is referred to as the Asteroid belt. They are rocky remnants left over from the early formation of our solar system about 4.6 billion years ago.

All the planets in your solar system rotate counterclockwise except for which planet?

Every planet except Venus and Uranus in our solar system rotates counterclockwise as viewed from above the North Pole of the planet. Venus has a slow clockwise rotation and Uranus rotates on its side.

Where are most asteroids in our solar system found in space?

Asteroids are found all over the solar system. The vast majority is located in the asteroid belt between the orbits of Mars and Jupiter.

Was Pioneer 1 the first man made object to leave the solar system?

There has never been a man made object to leave the Solar System. There are however, two objects which may escape the influence of Sol and enter the interstellar medium. These objects are the Voyager 1 and Voyager 2 spacecraft. It is currently unknown which will leave the system first, as although Voyager 1 was launched first, peculiarities of the nature of the Solar System may mean that Voyager 2 breaks the heliosphere first.

Which gases are there in our solar system?

Hydrogen, helium, nitrogen, oxygen, methane, carbon dioxide, neon, ammonia are some of them.

What is the nearest star to Earth and the center of your solar system?

The nearest star to the Earth is the Sun, the nearest Galaxy is the Milky Way, the one we live in.

How many hours is a year on Pluto?

Orbital period: ‎248.00 years; 90,560.0653 days; 2,173,441.5672 hours.

How did the sun and planetary system form?

The Sun and planetary system formed about 4.6 billion years ago from a giant molecular cloud of gas and dust. A disturbance, possibly from a nearby supernova, triggered the collapse of this cloud, leading to the formation of a rotating protoplanetary disk. The Sun formed at the center as material accumulated, while particles in the surrounding disk coalesced to form planets, moons, and other solar system bodies through processes of accretion and gravitational attraction.

What is Most of the mass of our Solar System contained in?

Most of the mass of our Solar System is contained in the Sun, which comprises about 99.86% of the total mass. The remaining mass is distributed among the planets, moons, asteroids, comets, and other celestial bodies, with Jupiter being the most massive planet. The Sun's immense gravitational pull governs the orbits of these objects and maintains the structure of the Solar System.

Is Earth heavier than Pluto?

Since Pluto is no longer considered a planet it is not likely to be able to determine equally the gravitational pull. On planets where the pull of gravity is greater than that of Earth, say Jupiter for instance, everything is heavier. A can of pop on Jupiter could weigh over 40 pounds. It is not likely that our bone structure could survive such a difference in gravity, but imagine being a Jupiter native visiting Earth. You'd feel light as a feather.
