1. A collision avoidance assistance device to assist avoidance of a collision between space objects among a plurality of space objects flying in space, the collision avoidance assistance device comprising:
a memory to store orbit forecast information, which is a forecast value of an orbit of each of the plurality of space objects; and
processing circuitry to:
determine whether space objects whose locations at a same time are in a dangerous relationship exist as danger-anticipated objects among the plurality of space objects, based on the orbit forecast information, and when it is determined that the danger-anticipated objects exist, output a danger alert indicating existence of the danger-anticipated objects; and
when the danger alert is output, decide that one of the space objects included in the danger-anticipated objects is to be an avoidance space object, which is a space object to perform an avoidance operation, and output an avoidance object notification to make a notification about the avoidance space object,
the processing circuitry is configured to decide which one of the space objects is to be the avoidance space object based on whether each space object included in the danger-anticipated objects is a rocket being launched.

9. A collision avoidance assistance method of a collision avoidance assistance device to assist avoidance of a collision between space objects among a plurality of space objects flying in space,
the collision avoidance assistance device including a memory to store orbit forecast information, which is a forecast value of an orbit of each of the plurality of space objects,
the collision avoidance assistance method comprising:
determining whether space objects whose locations at a same time are in a dangerous relationship exist as danger-anticipated objects among the plurality of space objects, based on the orbit forecast information, and when it is determined that the danger-anticipated objects exist, outputting a danger alert indicating existence of the danger-anticipated objects;
deciding that one of the space objects included in the danger-anticipated objects is to be an avoidance space object, which is a space object to perform an avoidance operation, when the danger alert is output, the deciding decides which one of the space objects is to be the avoidance space object based on whether each space object included in the danger-anticipated objects is a rocket being launched; and
updating an algorithm of an avoidance decision process of deciding the avoidance space object by machine learning using a result of deciding the avoidance space object.

10. A non-transitory computer readable medium storing a collision avoidance assistance program for a collision avoidance assistance device to assist avoidance of a collision between space objects among a plurality of space objects flying in space,
the collision avoidance assistance device including
a memory to store orbit forecast information, which is a forecast value of an orbit of each of the plurality of space objects,
the collision avoidance assistance program causing a computer to execute:
an alert control process of determining whether space objects whose locations at a same time are in a dangerous relationship exist as danger-anticipated objects among the plurality of space objects, based on the orbit forecast information, and when it is determined that the danger-anticipated objects exist, outputting a danger alert indicating existence of the danger-anticipated objects;
an avoidance decision process of, when the danger alert is output, deciding that one of the space objects included in the danger-anticipated objects is to be an avoidance space object, which is a space object to perform an avoidance operation, the avoidance decision process deciding which one of the space objects is to be the avoidance space object based on whether each space object included in the danger-anticipated objects is a rocket being launched; and
a machine learning process of updating an algorithm of the avoidance decision process of deciding the avoidance space object by machine learning using a result of the deciding the avoidance space object.

12. A collision avoidance assistance system to acquire space object information from a space information recorder that records space object information acquired from a management business device used by a management business operator that manages a plurality of space objects, and assist avoidance of a collision between space objects among the plurality of space objects, the collision avoidance assistance system comprising:
a database to store the space object information; and
a server including processing circuitry to decide a collision avoidance business operator that is to execute collision avoidance,
wherein the server includes
a phase of accepting, from the space information recorder, a notification notifying that a collision between a space object A and a space object B included in the plurality of space objects is foreseen;
a phase of acquiring, from the space information recorder, an estimated time or time period of the foreseen collision, orbit forecast information of the space object A, and orbit forecast information of the space object B;
a phase of notifying a danger alert, which is a collision alert or a proximity alert at the estimated time or time period, to at least one or all of a business operator of the space object A, a business operator of the space object B, and a debris removal business operator,
a phase of selecting a collision avoidance business operator; and
a phase of requesting the selected collision avoidance business operator to take a collision avoidance action,
wherein the space object information includes information indicating presence or absence of a collision avoidance function in a space object, and
wherein when both the space object A and the space object B have the collision avoidance function, the processing circuitry selects a collision avoidance business operator using whether each space object is a steady operation object or a non-steady operation space object as an evaluation criterion.
