Why has NASA sent recent orbiters to Mars on trajectories that required them to skim through Mars’s atmosphere before settling into their final orbits?

Why has NASA sent recent orbiters to Mars on trajectories that required them to skim through Mars's atmosphere before settling into their final orbits? It saves money because the spacecraft uses atmospheric drag to slow down rather than needing to carry enough fuel to slow by firing rocket engines.

What do we mean by the frost line when we discuss the formation of planets in the solar nebula?

What do we mean by the frost line when we discuss the formation of planets in the solar nebula? It is a circle at a particular distance from the Sun, beyond which the temperature was low enough for ices to condense.

How does the current theory of solar system formation explain why all the planets orbit the Sun in the same direction and in nearly the same plane quizlet?

– The formation of the spinning disk explains the orderly motions of our solar system today. The planets all orbit the Sun in nearly the same plane because they formed in the flat disk. The direction in which the disk was spinning became the direction of the Sun's rotation and the orbits of the planets.

What law of nature explains why the Sun should have been rotating after it formed from a collapsing cloud of gas?

What physical law explains why a cloud will rotate rapidly as it collapses? The nebular theory also predicts that the cloud should heat up as it collapses.

What is the primary basis on which we divide the ingredients of the solar nebula into four categories?

What is the primary basis upon which we divide the ingredients of the solar nebula into four categories (hydrogen/helium; hydrogen compound; rock; metal)? – The atomic mass numbers of various materials. – The amounts of energy required to ionize various materials.

Which of the following types of material can condense into what we call ice at low temperatures?

Which of the following types of material can condense into what we call ice at low temperatures? –Hydrogen compounds such as water, ammonia, and methane are gaseous at high temperature but condense into ice at low temperature.

Which of these upcoming observations will help test the idea that Mars' atmosphere thinned due to interactions with the solar wind? The upcoming MAVEN orbiter will measure present-day gas loss from Mars' atmosphere.

Why is the frost line important?

Frost line is the depth at which groundwater freezes. The ground contains moisture that is used by plants and animals to live and thrive, however, when cold weather hits, the groundwater begins to freeze and expand, pushing and crushing objects that are in the frozen dirt.

– The formation of the spinning disk explains the orderly motions of our solar system today. The planets all orbit the Sun in nearly the same plane because they formed in the flat disk. The direction in which the disk was spinning became the direction of the Sun's rotation and the orbits of the planets.

What is our best hypothesis for why all the planets in our solar system orbit in the same direction as the Sun rotates?

According to our theory of solar system formation, why do all the planets orbit the Sun in the same direction and in nearly the same plane? The laws of conservation of energy and conservation of angular momentum ensure that any rotating, collapsing cloud will end up as a spinning disk.

What are the two primary methods by which planets have been found around other stars in our galaxy?

What are the tow primary methods by which planets have been found around other stars in our galaxy? I) Direct images in visible and infrared light. II) Indirectly by detecting the motion of the host star.

What do we mean by accretion in the context of planet formation group of answer choices?

In astrophysics, accretion is the accumulation of particles into a massive object by gravitationally attracting more matter, typically gaseous matter, in an accretion disk. Most astronomical objects, such as galaxies, stars, and planets, are formed by accretion processes.

What percentage of the solar nebula’s mass consisted of hydrogen and helium gases?

About 2% of our solar nebula consisted of elements besides hydrogen and helium.

Why is the Sun important?

The sun is an ordinary star, one of about 100 billion in our galaxy, the Milky Way. The sun has extremely important influences on our planet: It drives weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis. Without the sun's heat and light, life on Earth would not exist.

How did the Earth form after the formation of the Sun?

Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.

Why is it important to build the footers and foundation walls below the frost line?

Once the bottom of your footings is buried below the frost line, the residual heat in the ground below the footing will ensure the soil below the footing will not freeze in the winter. The depth you are required to set your frost footings will vary from region to region across the country.

How deep are water lines buried in North Carolina?

12 inches deep In the Triad (as in most of North Carolina), water and sewer lines only need to be buried 12 inches deep. This is to accommodate the frost depth of the region, which rarely goes below nine inches. In the mountains, careful plumbers will install pipes closer to 18 to 24 inches, even though code only calls for 12.

Why is the nebular theory important?

The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the Sun.

How were the Sun and the planets in our solar system created?

The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.

Which hypothesis explains why all planets revolve around the Sun counterclockwise?

Answer: Most of the objects in our solar system, including the Sun, planets, and asteroids, all rotate counter-clockwise. This is due to the initial conditions in the cloud of gas and dust from which our solar system formed. As this gas and dust cloud began to collapse it also began to rotate.

What is today’s theory for why all the planets in our solar system orbit the Sun in the same direction and in roughly the same plane?

It's thought to have arisen from an amorphous cloud of gas and dust in space. The original cloud was spinning, and this spin caused it to flatten out into a disk shape. The sun and planets are believed to have formed out of this disk, which is why, today, the planets still orbit in a single plane around our sun.

Which new idea has been added into our theory of solar system formation as a result of the discoveries of extrasolar planets?

Which new idea has been added into our theory of solar system formation as a result of the discoveries of extrasolar planets? Planets can migrate from the orbits in which they are born.

How does the Kepler mission plan to detect Earth like planets around other stars?

How will the Kepler mission search for Earth-like planets? It will search for the dip in a star's brightness when an Earth-like planet transits (passes in front of) the star.

What is the meaning of accretion and how does it relate to the creation of our solar system?

In astrophysics, accretion is the accumulation of particles into a massive object by gravitationally attracting more matter, typically gaseous matter, in an accretion disk. Most astronomical objects, such as galaxies, stars, and planets, are formed by accretion processes.

What is the most important reason that astronomers have learned more about our planetary system in the last 30 40 years than all of history before then?

What is the single most important reason that astronomers have learned more about our planetary system in the last 30 years than all of history before then? We have been able to send spacecraft to visit many planets and satellites.

What kind of material in the solar nebula could condense at temperatures as high as 1500 K such as existed in the inner region of the nebula?

metals and rocks C) In the inner part of the nebula only metals and rocks were able to condense because of the high temperatures, whereas hydrogen compounds, although more abundant, were only able to condense in the cooler outer regions.

Why is sunlight important to living things?

The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
