  We are conducting a survey for extreme solar system objects to understand
Sedna and 2012 VP113 and determine if an unknown massive planet exists in the
outer solar system. Two new objects, 2014 SR349 and 2013 FT28, are extreme
detached trans-Neptunian objects, with a>150 AU and perihelia well beyond
Neptune (q>40 AU). Both new objects have orbits with arguments of perihelia
within the range of clustering of this angle for other extreme objects. One of
these objects, 2014 SR349, has a longitude of perihelion similar to the other
extreme objects, but 2013 FT28 is about 180 degrees away or anti-aligned in its
longitude of perihelion. We also discovered the first outer Oort cloud object
with a perihelion beyond Neptune, 2014 FE72. We discuss these and other
interesting objects discovered in our ongoing survey. All the high semi-major
axis (a>150 AU) and high perihelion (q>35 AU) bodies follow the previously
identified argument of perihelion clustering as first reported and explained as
being from an unknown massive planet by Trujillo and Sheppard (2014), which
some have called Planet X or Planet 9. Finally, with the discovery of 2013
FT28, we find that the longitude of perihelion is significantly correlated with
the argument of perihelion and orbit pole angle for all extreme objects. This
previous unnoticed correlation is further evidence of an unknown massive planet
on an eccentric inclined orbit, as extreme eccentric objects with perihelia on
opposite sides of the sky (180 degree longitude of perihelion differences)
would approach the inclined eccentric planet at opposite points in their
orbits, thus making the extreme objects prefer to stay away from opposite
ecliptic latitudes to avoid the planet (i.e. opposite argument of perihelia or
pole angles).
