The discovery of Charon around Pluto enabled astronomers to determine Pluto's mass
____________________ asteroids are the most common and appear to be the source of the most common type of meteorite, the chondrites. They are more common in the inner belt. S-type
_____________________ asteroids appear to have nickel-iron compositions and may be from the core of differentiated asteroids. M-type
A(n) ________________________ is a stony meteorite that contains no chondrules and no volatiles. They appear to have been melted after they formed and resemble solidified lava. achondrite
Once the nucleus of a comet begins to melt and vaporize, it produces a vast cloud of gas and dust called the coma

The three broad categories of meteorites are iron, stony-iron, stony

The impact of a large comet with Earth has been suggested to have caused the extinction of the dinosaurs. The impact site of this comet is in or near Chicxulub, Mexico
Of the following celestial objects, the one that is the most likely source of the gravitational disturbance that prevented the asteroids from forming a planet is Jupiter
A flash of light seen in the night sky is called a meteor
The Kuiper belt refers to the region of the solar system beyond the orbit of Neptune that is the source of short-period comets
The short-period comets do not have randomly oriented orbits because they formed in the Kuiper belt, a belt-shaped region in the plane of the solar system.
The ___________________________ meteorites are believed to have formed in the mantle of a large asteroid. achondrite
An asteroid has an orbital period around the sun of 5.2 years. How far from the sun is this asteroid? 3.0 AU
______________________ are round bits of glass found in some stony meteorites. Chondrules
____________________ asteroids are more common in the outer asteroid belt where it is cooler. They are darker and may be carbonaceous. C-type
Why is it believed that life cannot evolve on a planet that orbits a spectral type A, B, or O star? These stars do not remain on the main sequence long enough for life to evolve.
A cell’s DNA molecules are constructed of sugars, phosphates, and bases
Sugars, phosphates, and bases are the basic components that construct a spiral ladder-shaped molecule of a cell's DNA
Single stars are most likely to have planets suitable for life because these stars would allow planets to have stable orbits.
The first complex life appeared on Earth about 0.5 billion years ago during the ______________ period. Cambrian
DNA is coiled into a tight spiral and makes up the ___________________ that are genetic material in a cell. chromosomes
How can non-professional astronomers help with the SETI search? They can download a screensaver program that uses home computers to analyze SETI data.
