We present the results of a pencil-beam survey of the Kuiper Belt using the Keck 10 m telescope. A single 0.01 deg2 field is imaged 29 times for a total integration time of 4.8 hr. Combining exposures in software allows the detection of Kuiper Belt objects (KBOs) having visual magnitude mV ≲ 27.9. Two new KBOs are discovered. One object having mV = 25.5 lies at a probable heliocentric distance R ≈ 33 AU. The second object at mV = 27.2 is located at R ≈ 44 AU. Both KBOs have diameters of about… 

Large Bodies in the Kuiper Belt

We present a survey for bright Kuiper Belt objects (KBOs) and Centaurs, conducted at the Kitt Peak National Observatory (KPNO) 0.9 m telescope with the KPNO 8K Mosaic CCD. The survey imaged 164 deg2

The Kuiper Belt luminosity function from mR = 22 to 25

In summer 1999, we performed a survey optimized for the discovery of irregular satellites of Uranus and Neptune. We imaged 11.85 deg 2 of sky and discovered 66 new outer Solar system objects (not

A Wide-Field CCD Survey for Centaurs and Kuiper Belt Objects

A modified Baker-Nunn camera was used to conduct a wide-field survey of 1428 deg2 of sky near the ecliptic in search of bright Kuiper Belt objects and Centaurs. This area is an order of magnitude

The Size Distribution of Trans-Neptunian Bodies

We search 0.02 deg2 of the invariable plane for trans-Neptunian objects (TNOs) 25 AU or more distant using the Advanced Camera for Surveys (ACS) aboard the Hubble Space Telescope. With 22 ks per

Discovery of the Bright Trans-Neptunian Object 2000 EB173

We describe the discovery circumstances and photometric properties of 2000 EB173, now one of the brightest trans-Neptunian objects (TNOs) with opposition magnitude mR = 18.9 and also one of the

The Structure of the Kuiper Belt: Size Distribution and Radial Extent

The size distribution in the Kuiper Belt records physical processes operating during the formation and subsequent evolution of the solar system. This paper reports a study of the apparent magnitude

The Edge of the Solar System

We have surveyed for Kuiper Belt objects (KBOs) in six fields of the ecliptic (total sky area 1.5 deg2) to limiting magnitudes between R = 24.9 and R = 25.9. This is deep enough to detect KBOs of

Population of the Scattered Kuiper Belt

The discovery of three new scattered Kuiper Belt objects (SKBOs) from a wide-field survey of the ecliptic are presented, demonstrating that the SKBOs are similar in number and mass to the KuiPer Belt inside 50 AU.

A Deep Sky Survey of Edgeworth Kuiper Belt Objects with an Improved Shift-and-Add Method

A survey of the minor bodies in the outer regions of our solar system was carried out using the Suprime-Cam attached to the 8.2 m Subaru Telescope on Mauna Kea on 2001 February 22 and 25. Seven

Observational Limits on a Distant Cold Kuiper Belt

Almost all the more than 500 known Kuiper belt objects (KBOs) have been discovered within 50 AU of the Sun. One possible explanation for the observed lack of KBOs beyond 50 AU is that the distant
