Turn off the daylight and horizon displays. Open the
"Display" Palette and click on the left side of the "Stars"
button. Turn on "Limit by magnitude." Set the faintest magnitude
to 6.0, click Apply, then OK, then OK again. Click
on the "Goto" toggle on the horizontal toolbar. Set right ascension
and declination to 16h 11.4m and 33° 4.6° and then
click on "Center." Zoom in until the field of view is 10°.
Click on "File" and then "Print" to print a map of the region
of sky shown in the display. On the chart, mark the stars you
see in the display. One by one, double click on the stars
with the Selection Tool and record their temperatures and
luminosities. Decide which of the stars is most likely to
have planets. (Hint: eliminate all stars that aren't main sequence
stars with temperatures similar to the Sun's. Also
eliminate any star that has a binary companion closer than
10 seconds of arc.) The star you should have selected,
p Corona Borealis, is orbited by a planet about as massive as
Jupiter but with an orbit smaller than Mercury's.
