Focal .length . . . . . . . . . . . . The .distance .between .a .lens .(or .mirror) .and .the .point .at .which .the .image .of .an .

object .at .infinity .is .brought .to .focus. .The .focal .length .divided .by .the .aperture .of .
the .mirror .or .lens .is .termed .the .focal .ratio. .

Jovian .Planets . . . . . . . . . . Any .of .the .four .gas .giant .planets .that .are .at .a .greater .distance .form .the .sun .than .

the .terrestrial .planets.

Kuiper .Belt .. . . . . . . . . . . . A .region .beyond .the .orbit .of .Neptune .extending .to .about .1000 .AU .which .is .a .

source .of .many .short .period .comets.

Light-Year .(ly) . . . . . . . . . . . A .light-year .is .the .distance .light .traverses .in .a .vacuum .in .one .year .at .the .speed .

of .299,792 .km/sec. .With .1,557,600 .seconds .in .a .year, .the .light-year .equals .a .
distance .of .9.46 .X .1 .trillion .km .(5.87 .X .1 .trillion .mi). .

Magnitude. . . . . . . . . . . . . Magnitude . is . a . measure . of . the . brightness . of . a . celestial . body. . The . brightest .

stars .are .assigned .magnitude .1 .and .those .increasingly .fainter .from .2 .down .to .
magnitude .5. .The .faintest .star .that .can .be .seen .without .a .telescope .is .about .
magnitude .6. .Each .magnitude .step .corresponds .to .a .ratio .of .2.5 .in .brightness. .
Thus .a .star .of .magnitude .1 .is .2.5 .times .brighter .than .a .star .of .magnitude .2, .
and .100 .times .brighter .than .a .magnitude .5 .star. .The .brightest .star, .Sirius, .has .
an .apparent .magnitude .of .-1.6, .the .full .moon .is .-12.7, .and .the .Sun’s .brightness, .
expressed . on . a . magnitude . scale, . is . -26.78. . The . zero . point . of . the . apparent .
magnitude .scale .is .arbitrary. .

Meridian . . . . . . . . . . . . . . A .reference .line .in .the .sky .that .starts .at .the .North .celestial .pole .and .ends .at .the .

South .celestial .pole .and .passes .through .the .zenith. .If .you .are .facing .South, .the .
meridian .starts .from .your .Southern .horizon .and .passes .directly .overhead .to .the .
North .celestial .pole.

Messier . .. . . . . . . . . . . . . . A .French .astronomer .in .the .late .1700’s .who .was .primarily .looking .for .comets. .

Comets .are .hazy .diffuse .objects .and .so .Messier .cataloged .objects .that .were .not .
comets .to .help .his .search. .This .catalog .became .the .Messier .Catalog, .M1 .through .
M110.

Nebula .. . . . . . . . . . . . . . . Interstellar .cloud .of .gas .and .dust. .Also .refers .to .any .celestial .object .that .has .a .

cloudy .appearance. .

North .Celestial .Pole . . . . . . The . point . in . the . Northern . hemisphere . around . which . all . the . stars . appear . to .

rotate. .This .is .caused .by .the .fact .that .the .Earth .is .rotating .on .an .axis .that .passes .
through .the .North .and .South .celestial .poles. .The .star .Polaris .lies .less .than .a .
degree .from .this .point .and .is .therefore .referred .to .as .the .“Pole .Star”. .

Nova . . . . . . . . . . . . . . . . . Although .Latin .for .“new” .it .denotes .a .star .that .suddenly .becomes .explosively .

bright .at .the .end .of .its .life .cycle. .

Open .Cluster . . . . . . . . . . . One .of .the .groupings .of .stars .that .are .concentrated .along .the .plane .of .the .Milky .

Way. .Most .have .an .asymmetrical .appearance .and .are .loosely .assembled. .They .
contain .from .a .dozen .to .many .hundreds .of .stars. .

Parallax . . . . . . . . . . . . . . . Parallax . is . the . difference . in . the . apparent . position . of . an . object . against . a .

background . when . viewed . by . an . observer . from . two . different . locations. . These .
positions .and .the .actual .position .of .the .object .form .a .triangle .from .which .the .
apex .angle .(the .parallax) .and .the .distance .of .the .object .can .be .determined .if .the .
length .of .the .baseline .between .the .observing .positions .is .known .and .the .angular .
direction .of .the .object .from .each .position .at .the .ends .of .the .baseline .has .been .
measured. .The .traditional .method .in .astronomy .of .determining .the .distance .to .a .
celestial .object .is .to .measure .its .parallax.
